ProcessBase is a new persistent programming language targeted to support process modelling applications. It forms a central part of a compliant systems architecture, i.e. an architecture that is compliant to the needs of the running application. The ProcessBase Abstract Machine (PBAM) is the execution engine for the language. It uses a heapbased storage architecture together with two contiguous...

Coupons are collected one at a time from a population containing n distinct types of coupon. The process is repeated until all n coupon have been collected and the total number of draws, Y , from the population is recorded. It is assumed that the draws from the population are independent and identically distributed (draws with replacement) according to a probability distribution X with the prob...

This paper provides analysis to a generalized version of the coupon collector problem, in which the collector gets d coupons each run and he chooses the one that he has the least so far. In the asymptotic case when the number of coupons n goes to infinity, we show that on average n log n d + n d (m−1) log log n+O(mn) runs are needed to collect m sets of coupons. An efficient exact algorithm is ...

A novel bipolar transistor structure, namely, SiGe base lateral PNM Schottky Collector Bipolar Transistor (SCBT) in Silicon-On-Insulator (SOI) substrate is explored using two-dimensional (2-D) simulation. Based on a comparison with its equivalent PNP HBT, we demonstrate for the first time that the proposed SiGe base lateral PNM transistor exhibits a superior performance in terms of high current...

The DC and RF characteristics of double heterojunction bipolar transistors (DHBTs) with a compressively strained InGaAsSb base prepared by solid-source molecular beam epatixy (MBE) are investigated. Compared with conventional InGaAs/InP DHBT structures, the proposed InGaAsSb/InP HBT exhibits lower baseemitter turn-on voltage and VCE-offset voltage. Also observed are the high collector current d...

Simulated performance of packed bed solar energy storage system is reported in the present paper in continuation with Part-I and Part-II of this paper. The present part of the paper deals with system performance w.r.t. energy consumption by fan to propel air through the bed and thermal efficiency of solar collector. It is observed that energy consumption by fan and thermal efficiency of the col...

Current e-Learning is based on learning management systems that provide certain standard services course authoring and delivery, tutoring, administration and collaboration facilities. Rapid development of mobile technologies opens a new area of m-Learning to enhance the current educational opportunities. Field trips are a relevant part of the curriculum, but for various reasons it is often diff...

This paper analyzes the requirements and presents a novel approach to the development of a system for epidemiological data collection and integration based on the principles of interoperability and modularity. Accurate and timely epidemic models require the integration of large, fresh datasets. Thus, from an e-science perspective, collected data should be shared seamlessly across multiple appli...
