software Process Improvement (SPI) became known in the last twenty years. SPI is crucial to augment software process capabilities in software companies to face present demanding and global market. There were numerous published studies in United States, Europe, Australia and North America. Yet, there was still being short of research and published studies on SPI in Malaysia. This research attempts to fill this gap by focusing to analyze the resistance factors that de-motivate the implementation of SPI project specifically software companies operated in Malaysia. This research has been conducted during March 2008 until August 2008 and it used a survey instrument to gather data from 39 companies operated across Malaysia with the total of 251 professionals responded. The findings showed that organizational factors specifically human factors are playing an important role in determining the success of the SPI project. Participation and commitments from all individuals across the organization are also vital and imperative to ensure success for SPI initiative.

This paper presents our research towards efficient Demand Migration Systems (DMSs) in the General Intensional Programming System (GIPSY) environment. Basically, a DMS is the combination ofboth paradigms ofEvent-Driven Architecture and Message-Oriented Middleware. From the design perspective, a DMS is an instance ofthe Demand Migration Framework, which establishes the context to perform demand migration in the heterogeneous and distributed GIPSY environment. In this paper, we present our design and implementation approach to DMS based on JINI and JMS. Further, we benchmark these two versions by performing early experimental investigations to evaluate their behavior, capabilities and limitations for demand migration. The article concludes with a comprehensive conclusion, based on our experimental results.
We focus on defining context expressions in terms of initial syntax and semantics for an intensional MARF language, MARFL. It is there to allow scripting Modular Audio Recognition Framework (MARF)-based applications a...

In order to evaluate the structural complexity of class diagrams systematically and deeply, a new guiding framework of structural complexity is presented. An index system of structural complexity for class diagrams is given. This article discusses the formal description of class diagrams, and presents the method of formally structural complexity metrics for class diagrams from associations, dependencies, aggregations, generalizations and so on. An applicable example proves the feasibility of the presented method.

Deciding on how to evaluate each students programming skills is one of the largest challenges facing educators who teach object-oriented courses. Traditional assessment of programming education is with Grade. Quite often students get good grades in programming but still facing great challenges or have difficulties to take on real programming jobs. This research focus on how we addressed this challenge in object oriented programming course by proposing a new assessment method to assess students' object-oriented programming skills. The process begins by identifying generic object-oriented skills that students should acquired. In this paper we discuss the issues on object-oriented programming assessment and our proposed solution for a new assessment model. This followed by an approach taken in the process of identifying the object-oriented skills using Delphi technique. Delphi technique is a structured multi-step process that uses a group of experts to achieve a consensus opinion. We present the methodology of three Delphi processes to identify object-oriented programming skills. The identified skills will be used to guide both the coverage of student learning assessments and can be used by instructors to identify what topics merit emphasis.

Due to environmental mismatch, speech recognition systems often exhibit drastic performance degradation in noisy conditions. This paper presents a model-based technique termed Adaptive Parallel Model Combination (APMC) which compensates the initial acoustic models to reduce the discrepancy. APMC used the well-known PMC technique to composite a set of corrupted speech models, while fine tuning the mean parameter of the models using a transformation-based adaptation technique called Maximum Likelihood Spectral Transformation (MLST). Evaluated on a context-independent phone recognition task, APMC was found to be superior to both PMC and MLST, especially in non-stationary noisy conditions. On average, APMC has achieved 48.81% improvement over the initial models, whereas PMC and MLST have improved the accuracy by 34.12% and 35.23% respectively.
Producing software that is adaptable to the rapid environmental changes and the dynamic nature of the business life-cycle is extensively becoming a topical issue in the software evolution. In this context, change prop...
