TEACHING ARCHITECTURAL TECHNOLOGY WITH TECHNOLOGY (TEATWIT)

This paper is a reflection on a project that used Computer Aided Design (CAD) modelling to enhance the learning of architectural technology for 2nd year undergraduate students at the University of Cape Town in the 2010 academic year. A valuable grasp of architectural technology requires understanding of the subject as a construction system with technical limitations that offer creative freedom – a delicate balancing act between convention and innovation. Two buildings of technical and spatial-aesthetic repute were chosen for three dimensional CAD modelling: Fallingwater House (located in USA and designed by Frank Lloyd in 1936) and Die Es (located in South Africa and designed by Gabriel Fagan in 1965). The CAD models, taken from foundation to final roof finish, were elemental and sequentially incremental thus capable of illustrating, at varying scales, individual building components and how they relate to each other as well as to the whole building. The models were made into didactic resources comprised of (powerpoint-compatible) images and short movie clips. The representation precision, scale-shift and viewpoint-change possibilities of the dynamic 3D CAD models enhance understanding of building technology per se as well as comprehension of the reciprocal linkage of technical detailing to architectural spatialaesthetics. A significant number of students who engaged in the learning activities based on the created didactic materials displayed a holistic understanding of architectural technology that superseded a reductivist view of the subject.
The Application of Sensor Networks to Lighting Control

Abstract This paper evaluates the application of sensor networks to lighting control, and had two goals. The first goal was to evaluate the utility of using more than one sensor to detect occupancy. Sensor networks were installed in a sample of private offices and cubicle workstations. Large individual differences in sensor response to occupancy were observed in all monitored areas: the percent difference in occupied time measured by sensors in ten private offices ranged from 16.1 percent to 74.0 percent (mean 44.7 percent): the differences between detectors measuring occupancy in 23 cubicle workstations ranged from 14 percent to 91 percent (mean 53.7 percent). These data establish the considerable uncertainty in occupancy measurement that exists with current systems. Current control systems compensate for this uncertainty by applying a long time delay before switching lights off. Since a sensor network more accurately measures occupancy, shorter time delays can be applied to reduce system operating time and save energy. Applying a 5-minute time delay to sensor network data, instead of the 20 minutes that is more typical in current single sensor applications, reduced operating time by an additional 22.4 percent to 33.3 percent (relative to the reductions that would have resulted from use of a single sensor). A longer time delay of 10 minutes applied to the sensor network data stream produced reductions of 8.4 percent to 24.7 percent, relative to the reduction that would have resulted from use of a single sensor with a 20-minute time delay.

This paper presents some motivation of why studying PIM is important, the goals for the course, some sam- ple material from the course, and a few student evaluations. The paper presents in detail an activity called “Day in the Life of My Information” that resulted in an interesting experience from both, educational and research points of view.
Perencanaan Ulang Site Outdoor Coverage System Jaringan Radio GSM 900 dan 1800 di Semarang

Global System for Mobile Communication (GSM) is designed to provide solutions for high increasing number of subscribers of mobile communication services, while the frequency resources is limited. GSM is a digital cellular communication technology with a coverage service area is divided into small areas called cells, and each cell is handled by a site. To anticipate the growth of users number GSM system requires site re-planning that consist of three aspects, namely capacity, coverage and quality. With this site re-planning the number of site eficiency is expected. This final project has made a re-planning simulation for an outdoor coverage site system of GSM radio network 900 and 1800 in Semarang city, which has area of 373.67 km2 and consists of 16 districts and 177 villages, so it can serve customers until 2014. The first step in this final project is collecting data population and digital map of Semarang to be processed to obtain the estimated total population of Semarang in 2014 and the distribution of area types for every district. The second stage is analysis the RF Planning nominal which consists of analysis based on coverage requirement and traffic requirement. The coverage requirement analysis is based on link budget calculation and the cell radius calculation using Okumura-Hatta and Walfish-Ikegami outdoor propagation model. Traffic requirement analysis is based on traffic necessity and capacity of the site. The result of both analysis are then being compared and the biggest nominal RF planning is selected as the basis for next calculations to obtain a recommendation of the radio network design in Semarang. The third stage is site placement analysis. The used site in this design is the reuse partition sectorized system with a dual band frequency, in case of over traffic necessity, the optimization is done by using the technique of cell splitting. From that re-planning simulation for GSM 900 and 1800 radio network outdoor site coverage system in Semarang,can be known the needed number of sites to serve the customers until the year 2014 with a teledensity of 30%, i.e 91 sites with 250 Global System for Mobile Communication (GSM) sectoral cells and 230 Digital Cellular System (DCS) sectoral cells with the highest traffic for the micro cells occurred at sector 3, Sendangguwo village, District Tembalang that is equal to 132.36 Erlang, while the highest traffic for the macro cells occurred in Sector 3 Bamban Kerep village,District Ngaliyan which amounted to 66, 24 E.
Electrocortical Activity and Operator Workload: A Comparison of Changes in the Electroencephalogram and in Event-Related Potentials

Abstract : Pilot workload consideration are beginning to have a distinct cognitive emphasis, due to changes that are occurring in display formats and operating procedures. Consequently, new techniques for assessing workload must be developed that are more sensitive to fluctuations in attentiveness and in the capacity to time-share several system demands for processing, decision-making, and action. A flight simulation experiment was conducted in which pilots were trained to follow a commanded flight profile and maintain airspeed while concurrently performing threat avoidance and target acquisition tasks. Two types of brain electrical activity, event-related potentials (ERPs) and the 'ongoing' electroencephalogram (EEG), were analyzed in response to direct manipulations of difficulty in executing commanded flight maneuvers.
Design and full-wave analysis of supershaped patch antennas

The rapid development of wireless communication systems and the subsequent burst of wireless devices place several demands on the antenna designs. In particular, the development of high-performance radio systems require the adoption of broadband antennas featuring low profile, high gain, embedded installation and reduced manufacturing costs. Printed antennas, despite their inherent limitations can meet most of these requirements by employing innovative design solutions aiming at improving their electromagnetic performance. In this respect, a novel class of supershaped patch antennas is introduced and thoroughly investigated. The geometry of the proposed radiating structures is described by the polar equation known in the scientific literature as superformula or Gielis equation. Such equation can generate a large variety of different nature-inspired and abstract shapes which translates into the possibility of automatically reshaping the geometry of the radiating patch through the tuning of its parameters and consequently modifying the circuital performance and the radiation properties. In this context, the commercially available CST Studio Suite, based on the Finite Integration Technique (FIT), is used to perform the numerically based time domain full-wave analysis of the supershaped patch antennas. These simulations help to the deduction of useful conclusions upon the characteristics of general supershaped patch antennas as a function of the pertinent Gielis parameters. Moreover, a new developed semi-analytical method is used in order to obtain a meaningful physical insight to the operation of these antennas. At the end, we explore the possibilities of building novel high-performance antenna structures based on the supershape formula that are intended for modern applications. This investigation led in the conception of two dual-band supershaped patch antenna configurations designed for the WLAN IEEE 802.11a/b/g/n standards. The proposed planar designs are not only low-cost and simple to manufacture but also exhibit a plethora of attractive characteristics such as exact mathematical shaping definition, multi-band/wideband operation, very low cross-polarization levels, high radiation efficiency, frequency control capability, etc.
Method improvement of EMAT signals simulation and its applications in TBC inspection

In this paper, a code of finite element method is developed for numerical simulation of electromagnetic acoustic testing (EMAT) signals. In order to improve the simulation efficiency of ultrasonic field, a new explicit integration alg orithm of time domain is introduced in the simulation code. As an extending application of EMAT to the quality control of Thermal Barrier Coating (TBC), the feasibility of an EMAT transducer, which is proposed for detecting delaminating defect in TBC, is investigated by using the new code.
Structural and functional analysis of a phospho-dependent molecular switch: Rv1827 from Mycobacterium tuberculosis

Forkhead-associated (FHA) domains have gained considerable prominence as ubiquitous phosphothreonine-dependent binding modules; however, their precise roles in Ser/Thr kinase pathways and mechanisms of regulation remain unclear. From experiments with Rv1827, an FHA domain–containing protein from Mycobacterium tuberculosis, a complete molecular description of an FHA-mediated Ser/Thr protein kinase signalling process is derived. First, binding of the FHA domain to each of three metabolic enzyme complexes regulates their catalytic activities but does not require priming phosphorylation. However, phosphorylation of a threonine residue within a conserved N-terminal motif of Rv1827 triggers its intramolecular association with the FHA domain of Rv1827, thus blocking its interactions with each of the three enzymes. The nuclear magnetic resonance structure of this inactivated form and further mutagenic studies show how a novel intramolecular phospho-switch blocks the access of the target enzymes to a common FHA interaction surface and how this shared surface accommodates three functionally related, but structurally diverse, binding partners. Thus a remarkable and unsuspected versatility in the FHA domain that allows for the transformation of multiple kinase inputs into various downstream regulatory signals has been revealed.
Hemodynamic and Behavioural Changes in Older Adults During Cognitively Demanding Dual-Tasks

Background: Executive functions play a fundamental role in walking by integrating information from cognitive-motor pathways. Subtle changes in brain activation and behaviour may help identify older adults who are more susceptible to executive function deficits with advancing age due to prefrontal cortex deterioration. This study aims to examine how older adults mitigate executive demands while walking during cognitively demanding tasks.Methods: Twenty healthy older adults (M = 71.8 years, SD = 6.4) performed simple reaction time (SRT), go/no-go (GNG), n-back (NBK) and double number sequence (DNS) cognitive tasks of increasing difficulty while walking (i.e., dual-task). Functional near-infrared spectroscopy (fNIRS) was used to measure the hemodynamic response (i.e., oxy- [HbO2] and deoxyhemoglobin [HbR]) changes in the prefrontal cortex (PFC) during dual- and single-tasks (i.e., walking alone). In addition, performance was measured using gait speed (m/s), response time (s) and accuracy (% correct). Results: Using repeated measures ANOVAs, neural findings demonstrated a main effect of task such that ∆HbO2 (p = 0.047) and ∆HbR (p = 0.040) decreased between single- and dual-tasks. An interaction between task and cognitive difficulty (p = 0.014) revealed that gait speed decreased in the DNS between single- and dual-tasks. A main effect of task in response time indicated that the SRT response time was faster than all other difficulty levels (p < 0.001). Accuracy performance declined between single- and dual-tasks (p = 0.028) and across difficulty levels (p < 0.001) but were not significantly different between the NBK and DNS.Conclusion: Findings suggest that a healthy older adult sample might mitigate executive demands using an automatic locomotor control strategy such that shifting conscious attention away from walking during the dual-tasks resulted in decreased ∆HbO2 and ∆HbR. However, decreased prefrontal activation was inefficient at maintaining response time and accuracy performance and may be differently affected by increasing cognitive demands.
Fitting aerodynamics and propulsion into the puzzle

The development of an airbreathing single-stage-to-orbit vehicle, in particular the problems of aerodynamics and propulsion integration, is examined. The boundary layer transition on constant pressure surfaces at hypersonic velocities, and the effects of noise on the transition are investigated. The importance of viscosity, real-gas effects, and drag at hypersonic speeds is discussed. A propulsion system with sufficient propulsive lift to enhance the performance of the vehicle is being developed. The difficulties of engine-airframe integration are analyzed.
Polymorphism of MUC1 gene in Vietnamese gastric cancer patients: a case-control study

Background Gastric cancer is a malignant type of cancer associated with many factors such as environment, behavior, infection, and genetics, which include Single Nucleotide Polymorphism. A few studies revealed polymorphisms of the Mucin 1 gene have a role and significance as a susceptible factor contributing to gastric cancer. The aim of this research is to evaluate the association between Single Nucleotide Polymorphisms of the Mucin 1 gene and Vietnamese gastric cancer patients.Methods 302 gastric cancer patients and 304 controls were interviewed for social-economic characteristics, smoking and drinking status, personal and family history of gastric diseases. Genotyping was done using polymerase chain reaction-restriction fragment length polymorphism analysis. The association of Single Nucleotide Polymorphisms with gastric cancer was evaluated using multifactor regression models.Results AA genotype for rs4072037 was found to be highly associated with gastric cancer (OR: 2.07 (95% CI: 1.46-2.90). GG genotype for rs2070803 increased the risk of gastric cancer (OR:1.96 (95% CI: 1.37-2.78). These genotypes in combination with other factors such as old age, male gender, alcoholism and personal history of gastric disease also showed an increased risk of having gastric cancer.Conclusions rs4072037 and rs2070803 of Mucin 1 genes are two genotypic risk factors of gastric cancer. Those in combination with other factors such as gender, family history, smoking and drinking habits significantly increase the risk of gastric cancer.
CALCULATING CENTRE OF PRESSURE FROM MULTIPLE FORCE PLATES FOR KINETIC ANALYSES OF SPRINT RUNNING

Force plates are relatively small compared to athletes’ step lengths during sprint running. A large number of trials are subsequently rejected when collecting force plate data, which could be reduced by using multiple force plates. The aim of this study was to determine the suitability of foot contacts occurring across the boundaries of two force plates for use in inverse dynamics analyses. Centre of pressure data for a loaded wheel rolling across two force plates were compared to known positions of the wheel measured using an automated motion analysis system. A mean difference of 0.0027 [±0.0024] m was found between centre of pressure location and the measured wheel position as the wheel crossed the boundary between plates. The centre of pressure error resulted in joint power errors ranging from 0.27% to 1.47% for the ankle, knee and hip.
Smart Solution for Agriculture Leaf Disease

Agriculture is a very broad term encompassing all aspects of crop production,Livestock farming, Fisheries, Forestry etc. It may be defined as the art, the science and the business of producing crops and livestock for man’s use and employment. Agriculture is influenced by a large number of factors, some of which can be controlled by man(soil and irrigation) which others are beyond the control(climate). As we know Population pressure is increasing but area under cultivation is static, therefore more number of crops have to be grown on the same piece of land to increase the yield. As a result, intensive cropping has come into practice. for this purpose we are using the system which is pocket friendly as well as effective to the farmers. Through which they can get accurate information about their crop plants.
Cloud Computing Implementation Organizational Success in the Department of Defense

Abstract : The DoD tends to implement user based IT systems without quantifying whether those systems would be properly utilized by the target populous. Focus is generally emphasized on mission enhancement rather than looking at how or if it will be utilized by organizations. There would appear to be no reason for cloud computing to be implemented with the same disregard for acceptance and success. The day of large amounts of data is here and needs to converge with what this thesis investigates, the factors that positively influence organization acceptance and success of cloud computing specifically in the DoD so that is can properly maintain, utilize and store that data. This research focused in depth on that utilization.

Intestinal

Estimation of digestive enzyme activity, isolation and enumeration of aerobic microbial flora from the gastrointestinal tract of five brackishwater fish species (Mugil cephalus, Liza macrolepis, Mugil Lade, Chanos chanos, Lates calcarifer and Oreochromis mossambicus) of different feeding habits were carried out. The herbivorous (M. cephalus, C. chanos, M. Lade and L. macrolepis) and omnivorous (0. mossambicus) showed marked protease activity, whereas moderate protease activity was recorded in carnivorous L. calcarifer. In the herbivorous and omnivorous fish species the concentration of amylase was moderate to high. A very weak amylase activity was recorded in L. calcarifer. Cellulase activity has been found to be more pronounced in C. chanos, whereas, 0. mossambicus, M. cephalus, M. fade and L. macrolepis showed only moderate cellulase activity. Cellulase activity was weak in L. calcarzfer. Proteolytic, amylolytic, lipolytic and cellulolytic microflora were identified from the culture plates using selective media. The isolates were qualitatively screened on the basis of their extracellular enzyme producing ability. The selected isolates were further quantitatively assayed for protease, amylase and cellulase activities. Proteolytic activity was high in 0. mossambicus, whereas the activity of amylase and cellulase was high in the gastrointestinal tract of C. chanos. Protease activity was exhibited by almost all the bacterial isolates. Maximum activity of protease was exhibited by an isolate from L. macrolepis, followed by an isolate from L. calcartfer. Isolates isolated from 0. mossambicus and C. chanos exhibited high cellulase and amylase activity. Study indicated a distinct microbial source of the digestive enzymes (protease, amylase and cellulase) apart from endogenous sources in fish gut.
Information Assurance Cyber Ecology

Abstract : Cyber Ecology is a systems-level discipline addressing the emergent properties of computer networks and their responses to perturbations, such as attacks. It is a cross-disciplinary synthesis incorporating elements of biology, epidemiology, ecology, computer science, and system engineering. In this work, methodologies from epidemiology and ecology were applied to information assurance. The goals of the Cyber Ecology project were to: (1) enable and demonstrate the discovery of noel IA technologies for the detection and mitigation of damage due to cyber attack through the application of ecological models, (2) design, develop, document, evaluate and deliver methodologies to assess the behavior of computer networks from attacks by infectious agents and direct attacks, and (3) develop and demonstrate methods to make system-level assessments about network health. The work in this report spans four major areas: (1) definition and scope of Cyber Ecology, (2) application of ecological concepts to the classification of malicious code, in which insider threat is briefly discussed, (3) epidemiological applications of Cyber Ecology, and 94) system health expressed as emergent properties that can be assessed through evaluation of network (community) structure.
Big data algorithm optimization

When sales representatives and customers negotiate, it must be confirmed that the final deals will render a high enough profit for the selling company. Large companies have different methods of doing this, one of which is to run sales simulations. Such simulation systems often need to perform complex calculations over large amounts of data, which in turn requires efficient models and algorithms. This project intends to evaluate whether it is possible to optimize and extend an existing sales system called PCT, which is currently suffering from unacceptably high running times in its simulation process. This is done through analysis of the current implementation, followed by optimization of its models and development of efficient algorithms. The performance of these optimized and extended models are compared to the existing one in order to evaluate their improvement. The conclusion of this project is that the simulation process in PCT can indeed be optimized and extended. The optimized models serve as a proof of concept, which shows that results identical to the original system's can be calculated within < 1% of the original running time for the largest customers.
