Application of an Architect-Friendly Digital Design Approach to the Wind Environment of Campus Dormitory Buildings

Good natural ventilation can improve the comfort of campus dormitories and effectively avoid pollution caused by particle accumulation. Parametric design can effectively address the feedback and connection between building performance analysis and design. This study employs an architect-friendly digital design method based on the Rhino/Grasshopper parametric platform. It takes campus dormitories in the cold region as a case, using parameterized digital tools, such as the Butterfly plugin to simulate wind performance under three influencing factors: building layout, opening position, and building façade (shape and spoiler). Finally, the optimal design that can simultaneously meet the local winter and summer wind environment requirements is selected and validated. In addition, the reasonable design of external balconies and bathrooms in a dormitory can form buffer spaces to achieve effective wind shelter and insulation effects in cold regions. This article describes how to use digital tools to quickly and easily optimize the design of building forms based on wind simulations to promote campus sustainability.

Performance analysis of a novel solar assisted ground source heat pump water heating system with graded thermal energy storage

The solar assisted ground source heat pump system (SAGSHP) is recognized as an efficient, clean and economical renewable energy technology for hot water supply. However, in SAGSHP systems with an all-day hot water supply, the solar collectors can only heat the water tank with intense solar radiation, which wastes moderate and weak solar resources. In addition, as the SAGSHP system draws heat from the soil for a long time, the soil temperature around the borehole decreases, causing the performance of the GSHP to deteriorate. To solve the above problems, a SAGSHP system with graded thermal energy storage (SAGSHP-GTES) was proposed. This paper investigated the performance and feasibility of the SAGSHP-GTES system, using a case study of hot water supply in a campus dormitory in Changsha, China. Firstly, the drawbacks of solar energy utilization in the conventional SAGSHP system were analyzed. Then, the SAGSHP-GTES system was modeled by TRNSYS, and its operational performance was evaluated and compared with the conventional SAGSHP system. Finally, the feasibility and performance of the SAGSHP-GTES system in different climate zones of China were analyzed. The results showed that the conventional SAGSHP system had a poor solar energy utilization efficiency, with an average thermal efficiency of the SC (ηSC) of only around 19.4%. The long period of operation caused the soil temperature to drop from 18.1 °C to 2.78 °C, which led to a decrease in system efficiency and an increase in electricity consumption. By controlling the heat collection of the SC and the graded utilization of solar energy in the SAGSHP-GTES system, a high ηSC of around 42.7% was obtained, which improved the system efficiency while eliminating the problem of soil temperature drop. After 15 years of operation, the soil temperature increased from 18.1 °C to 19.9 °C, which led to an increase in the coefficient of performance of the system (COPsys) from 3.77 kW/kW to 3.84 kW/kW and COPGSHP from 3.45 kW/kW to 3.5 kW/kW, and a reduction in electricity consumption from 51,746 kWh to 50,735 kWh. In addition, the conventional SAGSHP system was not feasible in severe cold zones (Harbin) and cold zones (Beijing) of China, where soil temperatures fell below 0 °C and freezing of the circulating fluid occurred, while the SAGSHP-GTES system showed excellent performance in all climatic zones of China and is a feasible and efficient technology for hot water supply.

A Network Behavior-Based Botnet Detection Mechanism Using PSO and K-means

In today's world, Botnet has become one of the greatest threats to network security. Network attackers, or Botmasters, use Botnet to launch the Distributed Denial of Service (DDoS) to paralyze large-scale websites or steal confidential data from infected computers. They also employ “phishing” attacks to steal sensitive information (such as users’ accounts and passwords), send bulk email advertising, and/or conduct click fraud. Even though detection technology has been much improved and some solutions to Internet security have been proposed and improved, the threat of Botnet still exists. Most of the past studies dealing with this issue used either packet contents or traffic flow characteristics to identify the invasion of Botnet. However, there still exist many problems in the areas of packet encryption and data privacy, simply because Botnet can easily change the packet contents and flow characteristics to circumvent the Intrusion Detection System (IDS). This study combines Particle Swarm Optimization (PSO) and K-means algorithms to provide a solution to remedy those problems and develop, step by step, a mechanism for Botnet detection. First, three important network behaviors are identified: long active communication behavior (ActBehavior), connection failure behavior (FailBehavior), and network scanning behavior (ScanBehavior). These behaviors are defined according to the relevant prior studies and used to analyze the communication activities among the infected computers. Second, the features of network behaviors are extracted from the flow traces in the network layer and transport layer of the network equipment. Third, PSO and K-means techniques are used to uncover the host members of Botnet in the organizational network. This study mainly utilizes the flow traces of a campus network as an experiment. The experimental findings show that this proposed approach can be employed to detect the suspicious Botnet members earlier than the detection application systems. In addition, this proposed approach is easy to implement and can be further used and extended in the campus dormitory network, home networks, and the mobile 3G network.

Transition From Home to College Dormitory: The Role of Preestablished Affective Relationships in Adjustment to a New Life

Using 26-week longitudinal data on 61 female first-year college students, this study examined how the preestablished framework of social relationships of an individual student affect adjustment to the transition from home to the college campus dormitory. Based on an initial measurement, 23 agemate-dominant students and 14 family-dominant students were selected and compared in terms of how their new social relationships were formed and how their adjustment was supported by preestablished and/or new relationships. As predicted, the agemate-dominant-type students more easily developed relationships with new agemates and reported fewer difficulties in making the transition than their family-dominant-type counterparts. How the preestablished framework of social relationships moderated the present social interactions is discussed.

Make Policy—Not Coffee

Many college programs feature courses on women in government which rely on visiting politicians as guest lecturers on a one-shot basis. The unique feature of the Douglass program was that the two politicians-in-residence who shared teaching assignments were available to students informally at all times; they lived in a campus dormitory and took their meals at a student cafeteria. Students rarely come into contact with women in elective office because women have always been underrepresented in public life, says Ruth Mandel, director of the Center for the American Woman and Politics, which sponsored the course. Ms. Louise Conner predicts an increase in the number of women seeking political power. She feels a responsibility to teach them the political skills they will need to get away from stamp licking and envelope stuffing and into policy making. The Visiting Program in Practical Politics was aimed at raising the political consciousness of women.

A Comparison of Academic Aptitudes, Certain Values, and Personal and Background Characteristics of Students in Off-Campus Centers and on Central Campus of the Same University

THE MUSHROOMING college population is I creating many concerns for those responsible for higher education, the most imminent anxiety be ing the need for facilities and qualified faculties. Concurrently, college administrators and trustees who are charged with long-range planning are faced with the challenge to maintain standards of academic excellence which are consistent with the traditional and changing purposes of higher education. In an effort to accommodate the increasing number of applicants, Ohio's state universities have pursued a variety of potential solutions. Central campus dormitory provisions have been greatly expanded, deferred entrance policies were put into effect, and the academic center concept of off-campus instruction was adopted. It is the latter approach with which this study is concerned. The principal motivation for initiating off campus centers often results from the practical realization that campus facilities are inadequate to accommodate the swelling number of under graduate enrollments. Another popular motiva tion for developing these centers stems from the viewpoint that the opportunities for post high school education should be democratized further in this nation. However, apprehension exists about the preser| vation of admission standards when opportunities for higher education are diffused in a geographic area wider than the main campus. Faculty mem bers and the public often express the opinion that students who enroll in non-campus centers are less prepared and less competent than students who enroll on the central campus of the univer sity. This study was designed to provide empirical evidence to answer the question : Do students who attend undergraduate off-campus academic cen ters differ from students who attend the central campus of the university? Kent State University, the second largest of Ohio's state universities, with its eleven academic centers, offered a perti nent setting for this study. Although there have been several studies and publications about off-campus operations and the characteristics of college students in general, there is a dearth of research which compares the students of a central campus with off-campus students of the same university.
