Increase in environmental pollutions of fossil fuels calls for policies stimulating clean technology deployment especially in the transportation sector. To evaluate the efficacy of these policies we should explore the preferences of consumers regarding different technologies. In this paper we use a discrete choice approach used in “Canadian Integrated Model system” (SIMS) to identify the behavi...
There have been important changes in the United Kingdom’s (UK) fertility and immigration in the past decade, with a large share contributed by migrants from Poland. A detailed understanding of Polish migrant fertility is lacking, however, because the relevant data are not routinely collected. This paper provides new insights into the fertility patterns of Polish migrants in the UK, and compares...
The continuous tracking of mobile systems via active or passive RFID is a desirable but difficult to achieve objective. In this paper, we present our experimental results of positioning techniques using passive UHF RFID, Bluetooth, and WLAN. We thereby employ three orthogonal measuring techniques: detection rates, signal strength, and round trip time. The orthogonality of the methods is designe...
Java and related technologies are very used for distributed applications today. In this moment, there are many Java technologies using the client-server paradigm. Among these, the following are the most important: Common Gateway Interface (CGI) [4,7], Servlets/JSP [1,10,12], JavaSpaces [1,5,6] and Enterprise Java Beans (EJB) [1,2,8]. To choose one of these for solving a problem (to implement a ...
This article explains a new implementation of efficient D-Flip-Flop (DFF) using Gate-Diffusion-Input (GDI) technique, PowerPC, DSTC, and HLFF. This DFF design allows reducing power-delay product and area of the circuit, while maintaining low complexity of logic design. Performance comparison with other DFF design techniques is presented, with respect to gate area, number of devices, delay and p...
The three dimensional (3D) display technology has started flooding the consumer television market. There are a number of different systems available with different marketing strategies and different advertised advantages. The main goal of the experiment described in this paper is to compare the systems in terms of achievable Quality of Experience (QoE) in different situations. The display syste...
The future of mobile telephony is expected to rely on mobile services and the use of mobile services will be an integral part of the revenues to be generated by third generation mobile telephony. The adoption of new mobile services contradicts this proposition as it has been much slower than expected. Basic services such as search for information, ring tones, and icons and logos are still the m...
Less than thirty years after the giant magnetoresistance (GMR) effect was described, GMR sensors are the preferred choice in many applications demanding the measurement of low magnetic fields in small volumes. This rapid deployment from theoretical basis to market and state-of-the-art applications can be explained by the combination of excellent inherent properties with the feasibility of fabri...
