Discovering the invisible city: Game design for learning in technology enhanced places

In this paper we discuss the design of location-based mobile games supporting learning in technology enhanced public spaces. We describe the process of game design and we identify the main challenges faced. We briefly elaborate by discussing the case of Invisible City: Rebels vs Spies, a game to be played in a city centre. Through this case we highlight the adaptation of an original party game into a mobile game, the role of game narrative structure and user participation in game construction, and the key aspects conducive to learning. It is claimed that learning through mobile city games is a new challenge, as our city landscapes are augmented with an increasing number of layers of digital information in which a new generation of city games are played.
Modelling the Adoption and Use of Internet Technologies in Higher Education in Thailand

With a penetration rate of only about 13%, Internet usage in Thailand is lower than the world average, and is much less than the US and Australia where Internet penetration is over 70%. There are a number of approaches to modelling technology adoption, and this chapter describes a research project that modelled adoption of Internet technology by academics in Business Schools in Public Universities in Thailand. In the Internet adoption research outlined in this chapter, formulation of the research model was based mainly on TAM and its derivatives, survey methodology was used to collect primary data from academics in Thailand and analysis was performed using Structural Equation Modelling (SEM). The result was the generation of a research model: ‘The Internet Acceptance Model’ which demonstrates that only perceived usefulness, perceived ease of use and self-efficacy significantly influenced actual usage behaviour in this case.
Evaluation of an Interactive Campaign: Exploring the use of a motion-controlled game in a public space

This thesis project explores and evaluates the use of a motion-controlled game as an interactive campaign in a public space. Through a collaboration with the Trondheim-based company Global Illumination, we were given the task of developing a prototype that would be tested in the field. The objective was to evaluate the relevant technology, how users relate to the prototype and what the marketing potential is. Through a literature study and using the technology, we found that while it is still new, the technology is both mature enough to be used for several different platforms and languages, and cheap enough that the cost of getting started should not be a hindrance. We developed a game prototype using the OpenNI and XNA frameworks, in which people who pass by the display would be reflected on the screen in the form of a silhouette and automatically be a part of the game. The prototype was tested at four different public locations in Trondheim, and was evaluated mainly through observation and questionnaires given to both participants and non-participants. Our findings suggest that there is definite potential for using motion-control in interactive campaigns in public settings. The game attracted a good amount of attention, and seemed to pique the curiosity of passers-by. We saw a trend emerge where participants were comfortable with playing the game in public and were easily engaged. Children and young people in groups were by far the most active participants. We also found that keeping a low threshold for interaction was essential, as adding an extra step in the form of a wave gesture to participate reduced the number of participants considerably.
The design and construction of a solar incubator

Solar Incubator system utilizes solar energy to heat an incubating chamber for the process of fowl hatching. It is composed of: A solar collector which absorbs solar radiation (sunlight) and changes it into heat; A piping system which transfers the heat from the collector to a storage tank; The storage tank accumulates the hot water produced by solar energy so that it can be stored for use when needed; A number of accessories which ensure the regulation of the system; The sun's heat is used to warm water, which passes through the absorber-pipe element. The fluid is then fed to a water storage tank and helps provide hot water to the incubator. The solar incubator is designed to work for 24 hours a day. The collector is designed to heat water to the temperature of 50" C which is used to heat the incubator chamber to a temperature of 39.4" C by natural convection. It is designed to have a regulated humidity of 60%. The incubator has a capacity of 30 eggs.
Design and Implementation of Faster and Low Power Multipliers

A multiplier is one of the key hardware blocks in most digital and high performance systems such as FIR filters, digital signal processors and microprocessors etc. With advances in technology, many researchers have tried and are trying to design multipliers which offer either of the following- high speed, low power consumption, regularity of layout and hence less area or even combination of them in multiplier. Thus making them suitable for various high speed, low power, and compact VLSI implementations. However area and speed are two conflicting constraints. So improving speed results always in larger areas. So here we try to find out the best trade off solution among the both of them. Generally as we know multiplication goes in two basic steps. Partial product and then addition. Hence in this paper we have first tried to design different adders and compare their speed and complexity of circuit i.e. the area occupied. And then we have designed Wallace tree multiplier then followed by Booth’s Wallace multiplier and have compared the speed and Power consumption in them. While comparing the adders we found out that Ripple Carry Adder had a smaller area while having lesser speed, in contrast to which Carry Select Adders are high speed but posses a larger area. And a Carry Look Ahead Adder is in between the spectrum having a proper trade off between time and area complexities. After designing and comparing the adders we turned to multipliers. Initially we went for Parallel Multiplier and then Wallace Tree Multiplier. In the mean time we learned that delay amount was considerably reduced when Carry Save Adders were used in Wallace Tree applications. Then we turned to Booths Multiplier and designed Radix-4 modified booth multiplier and analyzed the performance of all the multipliers. After that we turned to different methods of power optimization, of which we could only complete a few like we went for designing different recoding schemes and their corresponding partial product generator scheme. After that we designed these recoders and PP generators and found out the time delays and area covered and power consumed by each scheme. We took into consideration that since all the PP generators take a huge amount of area we need to go for simplest of the designs for them and also side by side we need to ensure that we don’t have much switching actions in the circuit. After this we even modified one of the recoding schemes to lower the delay and power required by the circuit. The result of our project helps us to make a proper choice of different multipliers in fabricating in different arithmetic units as well as making a choice among different adders in different digital applications according to requirements. All the programs and results have been given in the following sections. Further work on Low Power Techniques on different multipliers needs to be done in order to make us choose a proper multiplier in accordance with the requirements by making the best possible trade off choice between Speed and Power in different circumstances.
On Detection of Current and Next-Generation Botnets

Botnets are one of the most serious security threats to the Internet and its end users. A botnet consists of compromised computers that are remotely coordinated by a botmaster under a Command and Control (C& C) infrastructure. Driven by financial incentives. botmasters leverage botnets to conduct various cybercrimes such as spamming, phishing. identity theft and Distributed-Denial-of-Service (DDoS) attacks. There are three main challenges facing botnet detection. First, code obfuscation is widely employed by current botnets, so signature-based detection is insufficient. Second, the C&C infrastructure of Botnets has evolved rapidly. Any detection solution targeting one botnet instance can hardly keep up with this change. Third, the proliferation of powerful smartphones presents a new platform for future botnets. Defense techniques designed for existing botnets may be outsmarted when botnets invade smart phones. Recognizing these challenges, this dissertation proposes behavior-based botnet detection solutions at three different levels—the end host, the edge network and the Internet infrastructure—from a small scale to a large scale, and investigates the next-generation botnet targeting smartphones. It (1) addresses the problem of botnet seeding by devising a per-process containment scheme for end-host systems; (2) proposes a hybrid botnet detection framework for edge networks utilizing combined host-and network-level information; (3) explores the structural properties of botnet topologies and measures network components' capabilities of large-scale botnet detection at the Internet infrastructure level: and (4) presents a proof-of-concept mobile botnet employing SKIS messages as the C&C and P2P as the topology to facilitate future research on countermeasures against next-generation botnets. The dissertation makes three primary contributions. First, the detection solutions proposed utilize intrinsic and fundamental behavior of botnets and are immune to malware obfuscation and traffic encryption. Second, the solutions are general enough to identify different types of but nets, not a specific botnet instance. They can also be extended to counter next-generation botnet threats. Third, the detection solutions function at multiple levels to meet various detection needs. They each take a different perspective but are highly complementary to each other, forming an integrated botnet detection framework.
Virtual OSGi Framework and Telecommunications

While embedded and telecommunication equipment is getting smaller, it is required to provide more functionality and flexibility. The success criteria for these equipments are often conflicting: lower cost but higher functionality and flexibility. A new emerging platform called OSGi Framework may be used to meet such high demands. Typical telecommunication or embedded devices for the OSGi Framework are most likely to have small form factor and design to be inexpensive for consumer market. Therefore, large or upgradeable memory may not be common. As the result, number of concurrent services is limited by the physical memory size. This paper proposes a solution to create a virtual memory like effect on the OSGi Framework to allow more concurrent services to run on the OSGi Framework platform. A hypothetical everyday life scenario is used to demonstrate how the Virtual OSGi Framework can be used to enhance the value of the standard OSGi Framework.
The MFE tank-floor scanner-a case history

The large storage tanks that are familiar features of oil terminals, refineries, chemical and petrochemical installations have problems with leaks caused by corrosion of their mild-steel floor plates. During scheduled routine inspections, it is highly desirable to find any active corrosion that could lead to failure before the next routine inspection. A DC magnetic flux leakage technique, referred to as magnetic flux exclusion (MFE) which was selected for such, the inspection is described. This application of MFE involves locally magnetising the floor plate with a trolley-mounted magnet and looking for anomalies in the field immediately above the floor surface caused by local loss of metal. No special surface preparation is required. >
Effectiveness of Using Cat-eye Reflectors as Warning and Traffic Calming Devices in Local Roads and Highways

Cat-eye reflectors are retroreflective safety devices that can be used effectively in road marking to provide directional guidance on roadways. This paper examines the effectiveness of using transverse cat-eye reflectors in the driving lane as warning and traffic calming devices. Field measurements of speed and in-depth interviews with different driver groups were used to assess the potential benefits of using cat-eye reflectors in these applications. The results show that cat-eye reflectors, when used as traffic calming devices in urban area, can effectively reduce the speed in local streets. However, they have a minor effect in reducing speed on highways. Cat-eye reflectors can also be used as warning devices on both highways and local roads to alert drivers about the need to take action. The results of in-depth interviews with drivers showed that drivers prefer cat-eye reflectors over other alternatives such as rumble strips. Heavy vehicle drivers seem to be the driver group that favors the use of cat-eye reflectors the most among other driver groups.
A Ubiquitous Optical Microsystem Platform with Application to Optical Metrology and Chemical Sensing

This dissertation is concerned with the development of a novel, versatile optical sensor platform for optical metrology and chemical sensing. We demonstrate the feasibility of embedding optical components between bonded silicon wafers with receptor cavities and optical windows to create a self-contained sensor microsystem that can be used for in-situ measurement of hostile environments. Arrays of these sensors internal to a silicon wafer can enable optical sensing for in-situ, real-time mapping and process development for the semiconductor industry in the form of an instrumented substrate. Single-die versions of these optical sensor platforms can also enable point-of-care diagnostics, high throughput disease screening, bio-warfare agent detection, and environmental monitoring. Our first discussion will focus on a single-wavelength interferometry-based prototype sensor. Several applications are demonstrated using this single wavelength prototype: refractive index monitoring, SiO2 plasma etching, chemical mechanical polishing, photoresist cure and dissolution, copper etch end-point detection, and also nanopore wetting phenomena. Subsequent sections of this dissertation will describe efforts to improve the optical sensor platform to achieve multi-wavelength sensing function. We explore the use of an off-the-shelf commercial RGB sensor for colorimetric monitoring of copper and aluminum thin-film etchings. We then expand upon our prior work and concepts to realize a fully integrated, chip-sized microspectrometer with a photon engine based on a diffraction grating. The design, fabrication, and demonstration of a working prototype with dimensions < 1 mm thick using standard planar microfabrication techniques is described. Proof-of-concept demonstrations indicate the working principle of dispersion, although with a low spectral resolution of 120 nm. With working knowledge of the issues of the first prototype, we present an improved 5-channel microspectrometer with a spectral range 400-900 nm and demonstrate its ability for spectral identification with 3 different phosphor powder samples. Finally, we conclude with suggestions for future areas of research.
Effects of a Shoulder Harness on Litter Carriage Performance and Post-Carry Fatigue of Men and Women

Abstract : The purpose of this study was to determine whether an ergonomically designed harness would improve soldier performance during and after litter carrying. Two litter carrying tasks were used: 1) a simulated mass casualty task; carrying and loading as many patients as possible within 15 mins and 2) a simulated removal from a remote site, carrying the litter at a constant rate of 4.8 km/hr for as long as possible, up to 30 min. Each task used a repeated measures design to determine differences in harness use, team size, and gender. Soldiers (12 men and 11 women) were measured on the following measures: rifle marksmanship, a fine motor task, heart rate and oxygen uptake while litter carrying, time of carry, number of carries, and ratings of perceived exertion. During the mass casualty task, men carried and loaded more patients than women (18 vs. 14 carries), and women reported greater soreness/discomfort than men post-carry. Using a harness resulted in faster fine-motor performance (47.6 vs. 46.1 sec) and lower subjective ratings of physical symptoms than with a hand carry.
Busting the Myth That Green Costs More Green

ABSTRACT Buildings are one of the largest consumers of resources and energy in this country, and according to the AIA (American Institute of Architects) are responsible for almost half of all carbon emissions in the United States. Since Americans spend nearly 90 percent of their lives indoors, buildings are clearly important to our way of life. The most common misconception about green building is that these approaches cost more to implement than traditional strategies and techniques of design and construction. Any decision made in the early stages of programming and design will have economic impacts on the overall building cost. How many floors will our building have? Will we use marble in the lobby? Can we use fancy fixtures in the bathrooms? But according to a Davis Langdon study, there was “…no significant difference in the construction costs for LEED®-seeking versus non-LEED® buildings…” In addition to this widely referenced report, other independent studies by the State of California and the GSA ind.
Advanced progress in calculating PFD for systems with PST

For Safety related systems the indication of the average probability of failure on demand (PFD) taking into consideration of he Proof Test interval is one possibility to compare different systems. In this paper we intend to derive the average PFD for a lool system taking into consideration as well the Proof Test as a Partial Stroke Test (PST). Thereby we specify a unique mathematic function without a helping probability band. Doing so, we get additional correlations between reduction of PFD and the diagnostic coverage factor and also of the PFD value between a system without PST and a system with PST. Finally we present an approximation in order to calculate the PFD value, if the ratio between the PST interval and the Proof Test interval is very small.
An exploratory case study using an expert learning process designed to promote number sense in a year 6 classroom

The purpose of this study was to explore how an expert learning process may be beneficial in developing number sense in Year 6 students. The expert learning process was a set of reflective prompts designed to include questions that expert learners consider. I chose to focus on the development of number sense due to its centrality in today's mathematics curriculum; and as it was a more specific topic, it made the task more manageable for this relatively small study. I used a case study method as this was an exploratory study and I was interested in gaining in-depth, rich material about one setting. The setting was a Year 6 class from a primary school in the Perth metropolitan area, and the study lasted for two school terms. The data collection method used a mixed paradigm designed in order to strengthen internal validity, although the predominant approach was qualitative. Using qualitative data collection it was found that by engaging in the expert learning process, the students were prompted to reflect on their learning at various times throughout the number lessons, thus beginning to behave as self-regulated learners. The expert learning process also made the students more motivated in their attitudes towards the mathematics lessons, and after reflecting on the prompts provided, the students were at times directed towards more effective learning strategies. The class teacher's teaching style was found to be extremely important in affecting the outcome of this study. Her transmissive teaching style meant that she did not perceive the students' reflections as important and therefore the learning environment was not influenced very much by these reflections. The students were powerless in this situation and had to accept the fact that their learning activities did not change greatly. The study was designed to find out if the number sense performance of the Year 6 students improved through using the expert learning process. To investigate this I took a quantitative approach using a number sense test, which had been used in
Knitted Wearable Stretch Sensor for Breathing Monitoring Application

Wearable technologies have been rapidly growing during the last decade. One of the most developed applications is the physiological and medical evaluation by using textile based sensors and electrodes. Sensors integrated into such a system are expected to be able to support the monitoring of personal activity during daily life and ensure the early detection of abnormal conditions such as sleep apnea which is a sleeping disorder phenomenon . Complete garment knitting is a one-step process, which enables to integrate the textile based sensor into a garment directly in the knitting process. The objective with this project was to design a weft knitted stretch sensor of different conductive yarns and structures. The performance of the sensors was evaluated by measuring the electrical resistance changes in the knitted structure as a function of elongation with a self-built cyclic tester. In addition, a prototype garment made by flat knitting machine has been made in order to evaluate the sensor performance as a breathing rate indicator.
Implementing Lean in higher education university

Lean means creating more value for customers with fewer resources, by minimizing waste. Although traditionally this concept is applied in manufacturing, the Lean management improvement principles can be also applied in the case of educational institutions. This paper presents three case studies of implementing Lean in UK and USA universities that can be useful examples for implementing Lean in any university environment
Investigation Of Material Properties Of KucukAyasofya Mosque-Sts Sergius And Bacchus OfIstanbul

Kucuk Ayasofya Mosque, Sts Sergius and Bacchus, is one of the oldest surviving monuments possessing its original structure in Istanbul. It was built in 527 A.D. durin the reign of Justinian and served as a Christian sanctuary for nearly a thousand years. In the investigation of the physical and mechanical properties of materials some non-destructive tests, as rebound tests and sonic tests, were applied and the relative humidity of the surfaces were measured on the exterior walls in winter and summer conditions. Some cores were taken out by drilling from the walls. In this paper the performance of the materials as result of the tests are evaluated.
