Minimizing the Maximum Length of Flight Paths for UAVs Providing Location Service to Ground Targets

When a UAV broadcasts its location periodically during flight, a target will observe the strongest signal when the UAV is at the closest location; thus, the target can infer its location based on the observed signals and the UAV’s trajectory. We consider how to design trajectories for UAVs such that all targets can locate themselves, and the maximum length of trajectories is minimized. To make the problem tractable, we impose constraints on the set of possible trajectories such that they only contain the edges of small squares. We propose an integer-linear-programming-based solution, which runs in exponential time, and two polynomial-time constant-factor approximation algorithms. We implement a prototype system to verify the feasibility of the localization method. Simulations show that our approach outperforms the existing ones in terms of flight length and localization error.

Aplikasi Web Service Berbasis Android untuk Pencarian Kost Lingkungan Kampus Universitas Indraprasta PGRI

Human needs are the reason technology is developing rapidly. One of the benefits of technological development is making information very easy to obtain. Everyone can get various kinds of information, such as searching for a list of houses, rented houses to boarding houses. Many people get that information easily, but not a few people have difficulty getting the same information. One example that often occurs is overseas students who find it difficult to get boarding information. Indraprasta University students complain that it is difficult to get information on boarding houses that are close to campus. From this problem, it prompted the author to create an Android-based Boarding House Search Application. In making this application the author uses Android Studio as a code editor, and exchanges data on the web service using JSON. Searching for boarding houses in this application uses two ways, first a boarding search based on a list and second a boarding house search based on the user's closest location. The menu on the main page makes this application easy to use by anyone.

Customer’s Behavior and Willingness to Pay for the Antioxidant Eggs

Chicken eggs enriched with antioxidants are produced to provide functional foods that are healthier to consume, with a premium price. The study was intended to analyze customers’ assessment, buying behavior, and willingness to pay the antioxidant (AO) chicken eggs. The study was conducted in Malang Regency, the closest location to the UMM Farm Business Unit. Primary data were obtained from interviews with customers of the AO and conventional eggs. The data were analyzed with a quantitative descriptive design and the t-test. The results suggested that customers assessed the AO chicken eggs had better nutritional content than the conventional one and produced a better impact on health. Customers’ behavior indicated that the purchase of the AO eggs was still lower than conventional eggs, although customers' tasting attitude on the AO egg portrayed a higher preference. Customers were willing to pay more expensive to the AO eggs. The price of AO eggs without any label was 7% higher than the conventional counterpart during the time of the study. If the AO eggs are labeled, they will take a premium price of 21% more than conventional eggs. The results recommended the producers to do packaging and labeling to the AO eggs to expand the market. Moreover, the UMM Farm needs to consider various packaging designs based on consumer preferences and determine the market penetration of the AO eggs.

Anthropometric Factors on Safe Distances between Popliteal Vessels to the Femur for Cerclage Wiring of the Distal Femoral Fracture: A Magnetic Resonance Imaging Study

Background and Objectives: The proximity of the popliteal vessels in the distal femur may increase the risk of iatrogenic vascular injury during cerclage wiring. In this study, the closest location and distance of the popliteal vessels to the femur was examined using magnetic resonance imaging (MRI). The associations between anthropometric factors and the distance that would guide the placement of wires safely during surgery were also identified. Materials and Methods: We reviewed adult knee magnetic resonance images and recorded: (1) the relation and the shortest horizontal distance (d-H) from the femoral cortex to the popliteal vessels in axial images and (2) the vertical distance (d-V) from the adductor tubercle to the axial level of the d-H values in coronal images. The effects of anthropometric factors (sex, age, body height, body weight, body mass index, thigh circumference, femoral length and femoral width) on these distances were analysed. Results: Analysis of 206 knee magnetic resonance images revealed that the closet locations of popliteal vessels were at the posteromedial aspect of the femur. The d-H and d-V were 7.38 ± 3.22 mm and 57.01 ± 11.14 mm, respectively, and were both shorter in women than in men (p < 0.001). Multivariate analysis identified thigh circumference and femoral length as the most influential factors for the d-H and d-V, respectively (p < 0.001). Linear regression demonstrated a strong positive linear correlation between the thigh circumference and the d-H and between the femoral length and the d-V (Pearson’s r = 0.891 and 0.806, respectively (p < 0.001)). Conclusions: The closet location and distance of the popliteal vessels to the femur provide useful information for wire placement during distal femoral fracture surgery while minimising the risk of vascular injury. Given that patients with a smaller thigh circumference and a shorter femoral length are more likely to have a smaller d-H and a shorter d-V, respectively, cautious measures should be taken in such cases.

Aplikasi Marketplace Penyewaan Lapangan Olahraga Dari Berbagai Cabang Dengan Metode Agile Development

Competition in sports field leasing is quite fast these days, making sports field managers improve facilities and provide competitive prices to attract sports field tenants. However, this progress was not accompanied by advances in technology so that sports field managers still had to do the manual method for field operations and promotion. On the side of the tenants of the sports field also still have to go to the sports field to find out the availability of schedules, facilities, and prices offered. Then many tenants who have an interest in exercising more than one branch of sport, therefore researchers use the concept of a marketplace that can bring together the managers of sports fields with field tenants in one container. In the application development process, it is done by using the agile method application development method because in its development it can be possible to collaborate and correct each other among team members to increase the customer satisfaction ratio. The application implementation uses the Laravel framework, PHP for programming language, and the MySQL for Database Management System. The results of the study can be concluded that the use of the marketplace concept can bring together prospective field tenants with many field managers and the ease of finding a sports field following the wishes of tenants by selecting the category of field, price and closest location and the manager of the sports field can promote the sports field by registering the field.

Vessel routing and optimization for marine debris collection with consideration of carbon cap

Marine debris pollution is becoming an increasingly serious problem, affecting not only navigational safety but also the health of marine ecosystems. Carbon emission causes ocean acidification, which greatly harms marine lives. In order to respond to these environmental issues, this paper studies marine debris collection with consideration of carbon cap using logistics network. To the most of our knowledge, this is first work to study marine debris removal from logistics way. We proposed a three-phase marine debris collection framework: (1) identifying initial locations of the debris; (2) utilizing GNOME software to predict the drifting trajectory of the debris; and (3) formulating vessel routing as a mixed integer nonlinear programming with consideration of carbon emission. The model seeks to minimize the total costs including fuel cost, berth cost, unloading cost in the harbor, vessel rent, vessel insurance, and labor cost, with respect to the constraints of carbon cap, vessel capacities, and time windows. After the linearization process, a Branch-and-Cut (B&C) algorithm with multiple variable fixing techniques and valid inequalities is used to solve the proposed model. The debris dispersion located in Boston vicinity is used as a case study to validate the proposed model and algorithm. The results reveal that the farther away the debris location is from the shore, the higher the collection cost and the more the carbon emission would be. The daily collection cost in the closest location and in the farthest location is $140 lower and $210 higher than that in the initial location. The carbon emission in the farthest location is 21% and 32% higher than that in the initial location and in the closest location. Sensitivity analysis is also carried out for the fuel price and carbon cap to test their impact on total costs These results show that proposed model and algorithm can significantly improve the efficiency of marine debris collection process, reduce carbon emission and total costs.

Seasonal variability of phytoplankton in river Słupia of the southern Baltic Sea

In the Baltic Sea, there can be observed seasonal variations in the structure of phytoplankton. These organisms are particularly sensitive to changes in different environmental parameters. The consequence of these changes is cyclical repeated every year fluctuation of the species composition, their abundance and biomass of phytoplankton. The spatial and temporal variability of individual phytoplankton groups is not the same in different regions of the Baltic Sea, and this is why the study was conducted in the area of the central Baltic coast, since in that particular region data on phytoplankton is not available. One of the main goals was to determine the temporal and spatial structure of the occurrence of phytoplankton, as well as to study biodiversity in the area of the estuary of the Slupia river in southern Baltic for the period between November 2014 and September 2016. The results of the research confirm typical changes of phytoplankton in three studied areas depending on the given season. The average values of phytoplankton abundance and biomass were typical for this kind of coastal waters and there were no significant species differences between these stations. The only research (and available studies) on phytoplankton in central sea basin areas is being conducted by Institute of Meteorology and Water Management (IMWM) as part of the HELCOM Baltic Sea Monitoring at station P16, which is the closest location to the studied area. When comparing the results obtained in this study to the data from the IMWM annual reports for the last decade, it can be noticed that the size and fluctuations of total biomass and phytoplankton abundance in the three studied areas are typical for the coastal region of the South Baltic.

The Development of Mobile Application to Introduce Historical Monuments in Manado

Learning the historical value of a monument is important because it preserves cultural and historical values, as well as expanding our personal insight. In Indonesia, particularly in Manado, North Sulawesi, there are many monuments. The monuments are erected for history, religion, culture and past war, however these aren’t written in detail in the monuments. To get information on specific monument, manual search was required, i.e. asking related people or sources. Based on the problem, the development of an application which can utilize LBS (Location Based Service) method and some algorithmic methods specifically designed for mobile devices such as Smartphone, was required so that information on every monument in Manado can be displayed in detail using GPS coordinate. The application was developed by KNN method with K-means algorithm and collaborative filtering to recommend monument information to tourist. Tourists will get recommended options filtered by distance. Then, this method was also used to look for the closest monument from user. KNN algorithm determines the closest location by making comparisons according to calculation of longitude and latitude of several monuments tourist wants to visit. With this application, tourists who want to know and find information on monuments in Manado can do them easily and quickly because monument information is recommended directly to user without having to make selection. Moreover, tourist can see recommended monument information and search several monuments in Manado in real time.

Mosses of southwest Ethiopian montane forests – notes on their occurrence pattern and many new country records

One hundred and thirty-nine taxa of mosses are reported from the montane forest zone of southwest Ethiopia. Of these, 53 taxa are new country records and Meteoriopsis reclinata (Müll.Hal.) M.Fleisch. ex Broth. is, in addition, new to Africa. Most of the new records are of species also found in Uganda, Kenya or Tanzania, but there are some surprises, such as Fabronia perciliata Müll.Hal. with the closest location in South Africa and Namibia, Entodontella cameruniae Broth. previously known only from West Africa and Bryomaltaea obtusifolia (Hook.) Goffinet, otherwise reported only from the Democratic Republic of the Congo. We list all taxa and give a short account of their frequency and in which habitat and on which substrate they grow. That such a large proportion of the species are new to the country suggests that Ethiopia is bryologically very under-explored, and that further exploration will reveal many additional species. In particular, the remnant forests of southwest Ethiopia are likely to be of great importance as bryophyte hotspots.

Microscale spatial analysis provides evidence for adhesive monopolization of dietary nutrients by specific intestinal bacteria.

Each species of intestinal bacteria requires a nutritional source to maintain its population in the intestine. Dietary factors are considered to be major nutrients; however, evidence directly explaining the in situ utilization of dietary factors is limited. Microscale bacterial distribution would provide clues to understand bacterial lifestyle and nutrient utilization. However, the detailed bacterial localization around dietary factors in the intestine remains uninvestigated. Therefore, we explored microscale habitats in the murine intestine by using histology and fluorescent in situ hybridization, focusing on dietary factors. This approach successfully revealed several types of bacterial colonization. In particular, bifidobacterial colonization and adhesion on granular starch was frequently and commonly observed in the jejunum and distal colon. To identify the bacterial composition of areas around starch granules and areas without starch, laser microdissection and next-generation sequencing-based 16S rRNA microbial profiling was performed. It was found that Bifidobacteriaceae were significantly enriched by 4.7 fold in peri-starch areas compared to ex-starch areas. This family solely consisted of Bifidobacterium pseudolongum. In contrast, there was no significant enrichment among the other major families. This murine intestinal B. pseudolongum had starch-degrading activity, confirmed by isolation from the mouse feces and in vitro analysis. Collectively, our results demonstrate the significance of starch granules as a major habitat and potential nutritional niche for murine intestinal B. pseudolongum. Moreover, our results suggest that colonizing bifidobacteria effectively utilize starch from the closest location and maintain the location. This may be a bacterial strategy to monopolize solid dietary nutrients. We believe that our analytical approach could possibly be applied to other nutritional factors, and can be a powerful tool to investigate in vivo relationships between bacteria and environmental factors in the intestine.

A Keleti-Bakony triász időszaki vulkanogén képződményeinek petrográfiai vizsgálata és képződési körülményeik értelmezése

A Tethys közép-európai triász időszaki fejlődéstörténetének nyomozása az egymástól távolabbi területeken található nem vulkanogén üledékes kőzetek összehasonlító vizsgálatával régóta eredményesen zajlik. A térben és időben is sokkal változatosabb kifejlődésű vulkanogén képződmények ezirányú vizsgálatában rejlő lehetőségek még messze nincsenek kihasználva. Ennek leginkább az lehet az oka, hogy ezeknek a hazai kőzeteknek a részletes kőzettani leírása még nem történt meg. Ladin vulkanogén törmelékes képződmények a Dunántúli-középhegységen belül a Keleti-Bakony területéről ismertek. Az itt található középső–késő-triász vulkanogén kőzetek részletes petrográfiai vizsgálata lehetőséget teremtett arra, hogy kőzettani alapon is összevessük más hasonló korú, képződésük idején egymáshoz sokkal közelebb elhelyezkedett Dunántúli-középhegységben és Déli-Alpokban megtalálható vulkáni képződményekkel.A vizsgált keleti-bakonyi összletek az inotai Hideg-völgy útbevágásában lévő egykori felszíni feltárásban, valamint a Várpalota Vpt–3 és a Bakonykúti Bút–2 fúrások anyagában tanulmányozhatók. A vulkanogén összlet két részre tagolható: az alsó részben uralkodóan vulkanit törmelékszemcsékből álló, szenesedett növénymaradványt és elszórtan crinoidea váztöredékeket tartalmazó finomszemcsés üledékes kőzetet, fölül vulkanit- és mészkőkavicsokat nagy mennyiségben tartalmazó, Daonella vázelemekben gazdag durvaszemcsés rétegcsoportot találhatunk. A vulkáni törmelék szemcsék között döntően intermedier (andezit), kisebb mennyiségben bázisos (bazaltsalak, bazalt és mikrodolerit) és savanyú (riolit, aplit) vulkanitok és ezekhez kapcsolódó kristálytörmelékek jelennek meg.A vulkanogén összlet forrását olyan középső- és felső-triász vulkáni kőzetek (bázisos-intermedier lávakőzetek és freatomagmás kitörések termékei) szolgáltatták, melyeknek mai rokon képviselői a Dunántúli-középhegységben (legközelebb a balatonfői területen), de legnagyobb kiterjedésben a vele ezen időszakban szomszédos Déli-Alpokban fordulnak elő. A felső vulkanogén konglomerátum / kavicsos homokkő képződésére jó analógia a déli-alpi Wengeni Formáció és Marmoladai Konglomerátum keletkezése. E formációk nagy vastagságú törmelékes összlete szárazulatra került, döntően mészkő és bázisos-intermedier kőzetek lepusztulásával, majd tenger alatti tömegmozgásokkal üledékgyűjtő medencékbe történő felhalmozódásával keletkezett. Az alsó vulkanogén homokkő keletkezése ettől némiképp eltér. Bázisos-intermedier összetételű törmelékanyaga első lépésben sekélytengeri/szárazföldi környezetben freatomagmás kitörés eredményeként halmozódott fel, majd közvetlen ezután tenger alatti lejtő mentén történő áthalmozódás után ülepedett le véglegesen.

Invasion of alien plants in fire-damaged forests at southern boundary of the taiga zone

Aim of study: Biological invasions are one of the most important areas of forest research. In this study, we revealed invasibility of fire-damaged forests at the southern boundary of the taiga zone.Area of study: The Mordovia State Nature Reserve (Central Russia).Material and Methods: Altogether, 11 square plots of each 100 ×100 m were established in different types of fire-damaged forests. To test plant invasion outside the established plots, field researches were carried out by route method in fire-damaged area of the Mordovia Reserve.Main Results: Six alien species (Erigeron canadensis, E. annuus, Oenothera biennis, Lactuca serriola, Sambucus racemosa, Viola arvensis) were registered within the established plots in 2011–2014. In addition, two alien invasive plants (Solidago canadensis and Bidens frondosa) were found outside these plots. No differences were detected in invasibility of the tested forest ecosystems.Research highlights: Among the revealed alien species, Erigeron canadensis, Lactuca serriola and Solidago canadensis are the most invasive plants in forest ecosystems. The first one was observed with a high occurrence frequency and abundance in all forest types tested. The second one has not been differed by abundance, but it characterized by a high competition as well as a large biomass and a large number of seeds. Solidago canadensis penetrated to natural forest ecosystem in a short time period due to closest location of its dispersal centers near the boundary of the Mordovia Reserve. These species are the most probable invaders of the forest ecosystems.Keywords: Invasive plants; invisibility; post-fire successions; Mordovia State Nature Reserve; wildfire; forest ecosystem.

Optimal routing of infiltration operations

This paper suggests a method for routing military ground operations, focused on conducting infiltration based on the shortest-path method. We model the problem in four parts. First, we estimate enemy locations by using public facility location model and military data, and use these to define possible enemy scenarios. Second, for each scenario, a shortest-path problem is solved, where each link’s cost is given by both “Speed” (Travel time) and “Surprise” (Detection probability). And the detection probability is jointly determined by the distance from the enemy’s closest location, detection device’s location and concealment probability from vegetation information. Third, the preferred solution is selected by a robust optimization process. The fourth step involves the use of dissimilar paths to incorporate the impact of a deception operation. The methodology is demonstrated by a case study that uses realistic data from South Korea.

A Survey Paper on Skyline Query using Recommendation System

Skyline query and recommendation system is more trendy in multi-criteria decision-making system, data mining and database field. Skyline query is used by numerous applications in recommendation i.e customised, collaborative and knowledge-based recommendation. Using skyline query in recommendation, the user finds the closest location based on his/her preference. Skyline query outlines dominated object. The dominance object suggests that an object is good or better than all dimensions or it is good at least in one dimension. Skyline operator extends the traditional database system. Skyline query is lot of fashionable in geo-spatial area. This paper survey is more attention-grabbing and still evolving research area, in order that the reader will simply acquire an outline of state-of-the-art. We have a tendency to review very well existing approaches that are applicable for geo-spatial location environment. Our analysis results in taxonomy of the existing approach. Finally, we tend to present fascinating research topic on skyline query using in recommendation that haven't explored.

Luzula effusa var. chinensis (Juncaceae): the first record for the wood-rush genus in Vietnam

Mount Fansipan, situated in the Hoang Lien Son Range, supports a rich subtropical and temperate flora of over 1700 species, including 25% of Vietnam’s endemic plant taxa (Nguyen &amp; Harder 1996, Sterling et al. 2006). At elevations above 2000 m, Mount Fansipan contains numerous temperate genera including Acer Linnaeus (19 spp., Sapindaceae Jussieu), Alnus Miller (A. nepalensis, Betulaceae Gray), Betula Linnaeus (B. alnoides Buchanan-Hamilton, Betulaceae), Carex Linnaeus (36 spp., Cyperaceae Jussieu), Clematis Linnaeus (9 spp., Ranunculaceae Jussieu), Lithocarpus Blume (13 spp., Fagaceae Dumortier), Quercus Linnaeus (9 spp., Fagaceae), Rhododendron Linnaeus (40 spp., Ericaceae Jussieu), Rubus Linnaeus (36 spp., Rosaceae Jussieu), Tsuga Carrière (T. dumosa Eichler, Pinaceae Sprengel ex F. Rudolphi), Ulmus Linnaeus (U. lancifolia Roxburgh, Ulmaceae Mirbel), Vaccinium Linnaeus (12 spp., Ericaceae), and Viola Linnaeus (12 spp., Violaceae Batsch) (Vietnam Plant Data Center 2015, Nguyen &amp; Harder 1996) with many of these genera being both species-rich and locally common (Nguyen &amp; Harder 1996, pers. obs.). In April 2012, a collection of a specimen, representing the temperate genus Luzula de Candolle (1805: 158), was made while conducting botanical studies on the Carex flora of Mount Fansipan, Lao Cai Province, Vietnam, which is about 30 km south of the border with Yunnan Province, China. While the specimen was immediately recognized as a Luzula, a new genus to the flora of Vietnam (Vietnam Plant Data Center 2015), it was not until our collection was identified using the keys in Wu &amp; Clements (2000) and Kirschner (2002) that it was determined to be Luzula effusa Buchenau (1879: 88) (Figs. 1, 2). A Basic Alignment Search Tool (BLAST) search of an internal transcribed spacer region (ITS1+5.8S+ITS2) sequence obtained from our specimen (KM612280) showed a 100% match with an existing sequence for L. effusa var. chinensis (Brown 1903: 161) Wu (1992: 92) (AY727778.1, see Drábková &amp; Vlcek 2010) in GenBank (National Center for Biotechnology Information 2014), supporting our identification based on morphology (Table 1). Eighteen other Luzula accessions, representing species placed in two different subgenera and four different sections, were found to have 100% coverage and 99% identity with the sequence from our specimen (National Center for Biotechnology Information 2014) (Table 1). In all cases, these sequences came from taxa that occur in regions that are more geographically disparate from Vietnam than the previously known closest location for L. effusa (see below). These taxa are also morphologically dissimilar to our specimen (see text below and Table 1).

Efficient preparation of orders in a distributor coffee company using tabu search

The article aims to develop a tabu search metaheuristic to solve the routing Travelling Salesman Problem (TSP) in the order picking process to obtain minimum distances when collecting products from the storage positions. The tabu search metaheuristic was implemented in the order picking of a coffee trading company in Antioquia, allowing the reduction of distance, time and cost of 44%, what amounts to a cost savings of $ 825000 a month and 825 minutes a month compared to a FLCL (Farthest Location -Closest Location) routing strategy, currently being used by the company, which allows to increase the efficiency of this operation.
