Stopkontak Pintar Berbasis Internet of things sebagai Solusi Manajemen Energi Listrik dengan Menggunakan Aplikasi Android

Leaving an electrical appliance connected to an outlet when not in use or on standby accounts for 80% of electricity wastage. A study conducted by the Lawrence National Laboratory, it was revealed that when a cellphone charger is still connected to a wall socket when not in use, there is still power being released. The purpose of this research is to make a smart socket based on the Internet of things (IoT) to be able to save electricity. An IoT smart socket that is designed to be integrated with an Android-based smartphone application. The IoT smart socket uses the ACS-712 current sensor and the ZMPT101B voltage sensor to measure electrical energy and then uses the Arduino Nano microcontroller and NodeMCU ESP8266 so that the socket can communicate with the Google Firebase cloud via Wi-Fi connection to the internet. The IoT smart socket uses a relay module as a switch, and the micro SD and RTC DS3231 modules record and store data (data logging) of electrical energy information that has been issued. The IoT smart outlet is integrated with Android smartphone applications created through Android Studio. The IoT smart socket in this study has 2 socket holes and features Wi-Fi pairing, electrical energy measurement, data logging, and socket scheduling (timer). The IoT smart outlet has an average measurement error of 3.27% when compared to a measuring instrument, and there is an error in the outlet timer feature with a delay of 5 to 30 seconds. The IoT smart socket is still said to be valid and can function properly.

Crack identification in concrete structures using implantable sensors

Although current sensing techniques have made remarkable achievements in solving many practical structural health monitoring problems, there exists a long-standing problem, that is, field sensors and systems cannot be easily deployed on concrete structures for sustainable and long-term monitoring owing to complex environmental impacts. This study investigates the development of an implantable sensor for crack identification in concrete. A multi-transducer integrated concrete implantable module (CIM) with the appearance of a wall socket is designed to provide a stress-wave scanning ability in concrete. A spherical piezoceramic shell (SPS) array with a diamond shape is embedded in the CIM that enables probing-signal energies to superimpose at the module surface. The functionality and performance of the CIM are studied numerically and experimentally. Four wavelet-packet-based damage indices are proposed to combine the data received for a comprehensive description of the degree of structural damage. The results show that the Euclidean distance yields the best positive linear correlation relative to the crack depths, and the Manhattan and Chebyshev distances have the potential to indicate the initial cracking process.

Automatic Pet Feeder with Solar PV System

Everything that has been done within the scope of this research is aimed towards designing a device with a solar voltage source, that is capable of directly and automatically feeding a pet animal by adhering to the schedule and conditions pre-determined by the user. The design utilizes the ESP8266 Wi-Fi module as a controller that receives weight data about the pet’s food inside a container. The Arduino also controls a servo that opens the container based on the parameters set by the user via a Blynk app in a smartphone. This system includes a relay to switch from a wall socket adapter power supply to a battery connected to a solar panel. The obtained results satisfy the purpose of the research. The device was able to operate well using the utility grid and it can last for two hours solely on a 12 V 6Ah lead-acid battery. The device is 100 % accurate in adhering to the user’s schedule, responding with an average delay time of 1.4375 seconds between the Blynk application to the ESP8266 system.

Evaluation of Fast Charging Efficiency under Extreme Temperatures

Multi-type fast charging stations are being deployed over Europe as electric vehicle adoption becomes more popular. The growth of an electrical charging infrastructure in different countries poses different challenges related to its installation. One of these challenges is related to weather conditions that are extremely heterogeneous due to different latitudes, in which fast charging stations are located and whose impact on the charging performance is often neglected or unknown. The present study focused on the evaluation of the electric vehicle (EV) charging process with fast charging devices (up to 50 kW) at ambient (25 °C) and at extreme temperatures (−25 °C, −15 °C, +40 °C). A sample of seven fast chargers and two electric vehicles (CCS (combined charging system) and CHAdeMO (CHArge de Move)) available on the commercial market was considered in the study. Three phase voltages and currents at the wall socket, where the charger was connected, as well as voltage and current at the plug connection between the charger and vehicle have been recorded. According to SAE (Society of Automotive Engineers) J2894/1, the power conversion efficiency during the charging process has been calculated as the ratio between the instantaneous DC power delivered to the vehicle and the instantaneous AC power supplied from the grid in order to test the performance of the charger. The inverse of the efficiency of the charging process, i.e., a kind of energy return ratio (ERR), has been calculated as the ratio between the AC energy supplied by the grid to the electric vehicle supply equipment (EVSE) and the energy delivered to the vehicle’s battery. The evaluation has shown a varied scenario, confirming the efficiency values declared by the manufacturers at ambient temperature and reporting lower energy efficiencies at extreme temperatures, due to lower requested and, thus, delivered power levels. The lowest and highest power conversion efficiencies of 39% and 93% were observed at −25 °C and ambient temperature (+25 °C), respectively.

Towards immersive designing of production processes using virtual reality techniques

The paper provides a novel approach to the implementation of virtual reality within planning and design of manual processes and systems. The use of hardware and software that is required to perform different production -- especially assembly -- tasks in a virtual environment, using CAD parts as the interactive elements, is presented. Considering the CAD parts, the format conversion problem is comprehensively described and solved using format conversion software to overcome the present poor data connectivity between the CAD system and VR hardware and software. Two examples of work processes have been made in a virtual environment: peg-in-hole and wall socket assembly. In the latter, the traditional planning approach of manual assembly tasks using predetermined motion time system MTM- 2 have been compared with a modern approach in which the assembly task is fully performed within a virtual environment. The comparison comprises a discussion on the assembly task execution times. In addition, general and specific advantages and disadvantages that arise in the immersive designing of production processes using virtual reality are presented, as well as reflections on teamwork and collaborative man-machine work. Finally, novel technologies are proposed to overcome the main problems that occur when implementing VR, such as time-consuming scene defining or tedious CAD software data conversion.

Airway trolley in the Emergency Department – A service development project case report

Background: Hamad General Hospital (HGH) houses the main Emergency Department (ED) in Qatar. This busy ED has a 27 bedded resuscitation area. Within a 24 hour period there could be any number between 1 to 10 cases that needed emergency or urgent intubation. Over the years, there has been multiple addition of new life saving devices to the resuscitation areas. All these devices add to the clutter of the already crowded resuscitation area, and may indirectly add to the chaos and occupational risk typically seen in a busy environment. Methods: We aim to develop an airway trolley (by re-cycling available parts in the hospital) which can accommodate all standard airway equipment and all of our current difficult airway devices – Glidoscope, Stortz CMAC video laryngoscope and Stortz Flexible Intubating Video Endoscope. Results: We created a robust and easy to clean trolley, with ample of work platform and storage spaces within easy reach. At the same time it is also small and mobile enough to tolerate our narrow resuscitation room floor space. It has multiple power sockets to charge all of the video intubating devices, and its main power cord is long enough to reach any wall socket without significantly obstructing medical staff movements. Conclusion: With the help of the Engineering Department, we managed to create an airway trolley that fulfills our exact requirement more than what we can find in the current medical equipment market. At the same time we also declutter our busy ED resuscitation room.

How much power does your server consume? Estimating wall socket power using RAPL measurements

Full system electricity intake from the wall socket is important for understanding and budgeting the power consumption of large scale data centers. Measuring full system power, however, requires extra instrumentation with external physical devices, which is not only cumbersome, but also expensive and time consuming. To tackle this problem, in this paper, we propose to model wall socket power from processor package power obtained from the running average power limit (RAPL) interface, which is available on the latest Intel processors. Our experimental results demonstrate a strong correlation between RAPL package power and wall socket power consumption. Based on the observations, we propose an empirical power model to predict the full system power. We verify the model using multiple synthetic benchmarks (Stress-ng, STREAM), high energy physics benchmark (ParFullCMS), and non-trivial application benchmarks (Parsec). Experimental results show that the prediction model achieves good accuracy, which is maximum 5.6 % error rate.

Wireless LAN at home, in institutions and organizations

Cheap and available wireless devices are commonly used at our home and in institutions. Wireless local area networks (WLAN), new type of networks set us free from problems of changing wall socket location. That kind of LANs makes access to the Internet more comfortable. We do not have to drill holes in walls and put cables to connect another workstation to the existing network. To avoid such problems we can plug the access point install wireless cards and use the wireless LAN to connect to the Internet. It is a good idea to go this way, but there are some questions associated with that: Are wireless networks secure?, Don't our data be eavesdropped by intruders?. That article depicts and explains steps that should be taken to build secure wireless LAN in different places, home institutions and financial institutions with top-secret data. The currently used methods of protecting WLAN from unwanted access are presented here. The article presents also some non-standard safeguards.

Antigravity glitter build a levitating disco-ball night-light; bell-bottom pants optional

In 1979, when I was 11 and enthralled by Star Wars, magnetism held a special appeal. It was closest thing in real world to the Force. So for our fifth-grade science project, a friend and I wrapped my dad‚s iron chisel with wire to make an electromagnet. When connected to a lantern battery, it grabbed, repulsed, and spun bar magnets like magic. But when we got curious and plugged it into a wall socket, resulting pop and puff of smoke produced an unforgettable jolt. The experience sparked a lasting fascination with magnetism. So when my son Liam, contemplating what to make for his own fifth-grade science fair, suggested making a magnetic levitation gizmo, I was irresistibly drawn to idea. The project turned out to be surprisingly challenging. Initially, we envisioned some simple circuitry that would make a miniature space ship from Star Trek (actually a Christmastree ornament) hover with no strings attached. How hard could it be?

NPlug: An Autonomous Peak Load Controller

The Indian electricity sector, despite having the world's fifth largest installed capacity, suffers from a 12.9% peaking shortage. This shortage could be alleviated, if a large number of deferrable loads, particularly the high powered ones, could be moved from on-peak to off-peak times. However, conventional Demand Side Management (DSM) strategies may not be suitable for India as the local conditions usually favor inexpensive solutions with minimal dependence on the pre-existing infrastructure. In this work, we present a completely autonomous DSM controller called the nPlug. nPlug is positioned between the wall socket and deferrable load(s) such as water heaters, washing machines, and electric vehicles. nPlugs combine local sensing and analytics to infer peak periods as well as supply-demand imbalance conditions. They schedule attached appliances in a decentralized manner to alleviate peaks whenever possible without violating the requirements of consumers. nPlugs do not require any manual intervention by the end consumer nor any communication infrastructure nor any enhancements to the appliances or the power grids. Some of nPlug's capabilities are demonstrated using experiments on a combination of synthetic and real data collected from plug-level energy monitors. Our results indicate that nPlug can be an effective and inexpensive technology to address the peaking shortage. This technology could potentially be integrated into millions of future deferrable loads: appliances, electric vehicle (EV) chargers, heat pumps, water heaters, etc.

Design Exploration of a Microcontroller Based RF Remote Control 13amps Wall Socket

This research work presents the design and implementation of a microcontroller based RF remote control 13Amp wall socket. The project is designed to control electronic devices that are connected to an ac power supply through the RF remote wall socket by turning the wall socket ON/OFF using the RF remote control whose operation is independent of the direction/positioned, unlike the Infra red remote control which uses" line of sight" . The project consists of the 89c52 microcontroller interfaced with" KYL-500S" micro power wireless transceiver data module and connected with an electromagnetic relay which turns the switch OFF with open contact and turns it ON with closed contact. The remote control transmits radio frequency signals which are received by the receiver of the wall socket and decoded by the microcontroller which now turns the relay ON or OFF.

The anatomy of the ACL and its importance in ACL reconstruction

The anterior cruciate ligament (ACL) anatomy is very significant if a reconstruction is attempted after its rupture. An anatomic study should have to address, its biomechanical properties, its kinematics, its position and anatomic correlation and its functional properties. In this review, an attempt is made to summarize the most recent and authoritative tendencies as far as the anatomy of the ACL, and its surgical application in its reconstruction are concerned. Also, it is significant to take into account the anatomy as far as the rehabilitation protocol is concerned. Separate placement in the femoral side is known to give better results from transtibial approach. The medial tibial eminence and the intermeniscal ligament may be used as landmarks to guide the correct tunnel placement in anatomic ACL reconstruction. The anatomic centrum of the ACL femoral footprint is 43 % of the proximal-to-distal length of lateral, femoral intercondylar notch wall and femoral socket radius plus 2.5 mm anterior to the posterior articular margin. Some important factors affecting the surgical outcome of ACL reconstruction include graft selection, tunnel placement, initial graft tension, graft fixation, graft tunnel motion and healing. The rehabilitation protocol should come in phases in order to increase range of motion, muscle strength and leg balance, it should protect the graft and weightbearing should come in stages. The cornerstones of such a protocol remain bracing, controlling edema, pain and range of motion. This should be useful and valuable information in achieving full range of motion and stability of the knee postoperatively. In the end, all these advancements will contribute to better patient outcome. Recommendations point toward further experimental work with in vivo and in vitro studies, in order to assist in the development of new surgical procedures that could possibly replicate more closely the natural ACL anatomy and prevent future knee pathology.

A Heterogeneous, Purpose Built Computer Architecture for Accelerating Biomolecular Simulation

Molecular dynamics (MD) is a powerful computer simulation technique providing atomistic resolution across a broad range of time scales. In the past four decades, researchers have harnessed the exponential growth in computer power and applied it to the simulation of diverse molecular systems. While simulations are currently approaching the hundred-thousand-atom, millisecond-timescale mark using large-scale computing centres, many interesting research topics are still beyond the reach of practical computational biophysics efforts.The purpose of this work is to design a high-speed MD machine which outperforms standard simulators running on commodity hardware or on large computing clusters. In pursuance of this goal, an MD-specific computer architecture is developed which tightly couples the fast processing power of Field-Programmable Gate Array (FPGA) computer chips with a network of high-performance CPUs. The development of this architecture is a multi-phase approach. Core MD algorithms are first analyzed and deconstructed to identify the computational bottlenecks governing the simulation rate. High-speed, parallel algorithms are subsequently developed to perform the most time-critical components in MD simulations on specialized hardware much faster than is possible with general-purpose processors. Finally, the functionality of the hardware accelerators is expanded into a fully-featured MD simulator through the integration of novel parallel algorithms running on a network of CPUs. With initial acceleration efforts focused primarily on expensive nonbonded force calculations, an architecture was developed whereby a single machine achieves the performance equivalent of an 88-core InfiniBand-connected network of CPUs. Finally, a methodology to successively identify and accelerate the remaining time-critical aspects of MD simulations is developed. This leads to an architecture with a projected performance equivalent of nearly 150 CPU-cores, enabling supercomputing performance in a single computer chassis, plugged into a standard wall socket.

Automatic cable spooling for a robotic vacuum cleaner

The main purpose of this paper is to create a mechanism that can automatically gather and loosen the power line on the mobile cleaning robot. A single-chip Microcontroller PIC18F452 is used as a control core in the robot. The robot driven by two stepping motors is equipped with six infrared-ray-distance detectors to detect obstacles and calculate the real distance between the sensor and obstacles. Moreover, a cable rewinding/loosening controller with a three-directional tension detecting switch is used to detect the appropriate rewinding/loosening. A cable-tray used to gather the cable is driven by a DC motor. The electric power of the robot is supplied by four sets of 12 v Pb-made batteries. The vacuum cleaning robot's plug-in action will be performed after the edge-searching is completed. The sweeping mode is started up and a s-type sweeping path is executed. The cable will be adjusted by using the cable rewinding/loosening controller during the vacuumcleaning process. The robot will rewind the cable while moving back to the wall socket if the ground-cleaning is completed. Experimental results reveal that the robot can rewind and loosen the cable effectively during the vacuum-cleaning process.

Risque de trouble du rythme et électrisation par courant domestique

Analysis of domestic low-voltage (220-240 V) electrical injury in children admitted to a pediatric emergency department to illustrate the low risk of initial or delayed risk of arrhythmia. Retrospective study between 2001 and 2008 analyzing all children aged less than 15 years admitted for a low-voltage electrical injury. The data collected were age, sex, time and circumstances of the accident, time and day of admission, transport modalities, presence of risk factors for arrhythmia (transthoracic current, wet skin, tetany, loss of consciousness or neurological symptoms, and initial EKG abnormalities), injuries, EKG, muscular and/or cardiac enzyme values, progression and complications. For statistical analysis, data were entered in Microsoft Excel tables. Analysis was done with StatView5.1 (SAS Institute) and Epi Info 6.04fr (VF, ENSP epiconcept). In the descriptive analysis, the data are presented as mean values with SD, median and range. Forty-eight children were included. The mean annual number of admissions was equal to 6 (range, 3-12). The mean age was 6.2 + or - 4.3 years (median, 4.6 years). There was a male predominance: the overall sex ratio was 1.5, i.e., 3 before the age of 2 and 2.6 before the age of 10. The electrical injury occurred after contact with a wire or a connected cord or after the introduction of a metallic object in a wall socket. Ten children had risk factors of arrhythmia (mainly wet skin or thoracic pain). Twenty-nine children suffered from burns to the extremities (digits and hands, 70 %). At admission, 45 children had an EKG performed. The initial EKG was considered abnormal in 8 cases showing: sinusal tachycardia (n=4), incomplete right bundle branch block (n=4), and V(1) negative T waves (n=1). The EKG normalized within the first 12h. Hospitalization for cardiac monitoring was required for 18 children. No delayed arrhythmia occurred. In a mean time of 3.5h after the accident, a troponin dosage was given to 15 children and was normal in all cases. One child developed rhabdomyolysis and evolved without needing dialysis. After a low-voltage electrical injury, initial arrhythmia is not frequent, with often a nonspecific and transitory EKG expression; delayed arrhythmia is very rare. Children presenting to the emergency department after such an electrical accident, who are asymptomatic, without any risk factors for arrhythmia (wet skin, tetany, vertical pathway of the current, preexistent cardiological conditions, loss of consciousness) and with a normal initial EKG do not require cardiac monitoring.

Discharged

General Motors' Chevrolet Volt is a car known as a plug-in hybrid because it will get most of its power from the wall socket in a garage. The Volt is bold, cool, and technically feasible. It appeals to early adopters, and it's catnip for the automotive fan mags. To cap it off, a little creative accounting gives it the sheen of sky-high mileage, the better to offset GM's gas-guzzlers and thus meet future fuel efficiency targets. GM, stung by the failure of its EV1 all-electric car of yesteryear, has put its considerable corporate muscle into the Volt, building the car into a game-changing breakthrough. But to succeed on those terms, it'll have to become a mass-market car-anything less wouldn't make enough of a difference to a company that, even in its postbankrupt state, still remains the second-biggest automaker in the world. And at a projected price of US $40,000, cosmic success just isn't going to happen.

VADs are not without adversity, however, as high post-operative morbidity and mortality are of major concern. For those who survive, little is known about the experience from the patients' perspective. The purpose of this qualitative, descriptive study was to gain a better understanding of the experience of living with a VAD Method(s): Through the process of open-ended interviewing, data were collected and analyzed on an ongoing basis to generate conceptual categories. A key informant articulated his experience of living with a VAD through his analogy to Edgar Allen Poe's The Pit and the Pendulum. Furthermore, language of co-informants corresponded closely with themes emerging in Poe's short story. During analysis, a consultant from the English Department provided additional analysis of The Pit and the Pendulum as it related to each theme. Results: Six adults with an average age of 58.8 years participated. Both men were Caucasian; two women were Caucasian and two were African-American. There was wide variation in the length of device implantation. Four key themes: Facing the Unknown, Feeling Confined, Living with Fear, and Hope for the Future emerged. Discussion: Comparison of the experience of living with a VAD to the tale of Poe's Narrator does not provide an easy image for nurses who care for this population. Yet, diagnosis of heart failure can, in fact, be a sentence of sorts: a sentence to an uncertain future, physical decline, even to death. The findings of this study can help clinicians to target interventions toward reducing the uncertainty associated with living with a VAD, providing opportunities to reduce the sense of confinement, recognizing and reducing patient fears, and providing and supporting hope for the future through reduction of symptoms and extending life or through providing a peaceful death.
