The present study was conducted to find out the prevalence of malaria in human population of selected four villages of district Okara, province Punjab, Pakistan. Malaria is endemic from the last few years in this area. Blood samples were collected by passive case detection method from four private clinics and a major Basic Health Unit (BHU). Prevalence was determined using slide positivity rate...

The increasing adoption of process-aware information systems (PAISs) has resulted in large process model collections. To support users having different perspectives on these processes and related data, a PAIS should provide personalized views on process models. Existing PAISs, however, do not provide mechanisms for creating or even changing such process views. Especially, changing process model...

Usability capability models are used for assessing the ability of development organisations to develop usable products. We have identified quality criteria for usability capability models and analysed the strengths and weaknesses of the existing models. The analysis reveals that there are differences both in the quality of the structure of the models and in the extent that they cover phenomena ...

background: the aim of this study is to develop a new ergonomics chisel based on user centered design approach and to evaluate the effectiveness for reducing awkward posture using catia software for simulation analysis. methods: respondents were selected using purposive sampling – age 18 – 49 years old, men, experience using chisel (>1 month). a set of questionnaire were used to interview worke...

Nowadays almost all retrieval algorithms (for text, images, drawings, etc.) are mainly concerned in achieving good system-centered measures, such as precision and recall. However, these systems are used by users, who try to achieve goals through the execution of tasks. To better satisfy the users’ needs we must involve them in the development process of the retrieval systems. In this paper, we ...

The wear mechanisms of cutting tools made of tungsten-carbide (WC), PCBN and PCD were investigated using the tool life and temperature results available in the literature. For tool/work combinations WC/steel and PCBN/hardened-steel, under practical conditions, tool wear was found to be greatly influenced by the temperature. It was concluded that the most likely dominant tool wear mechanism for ...

In previous work, we have argued that constraints on the relationships between requirements elements and design elements can be used to guide designers in making design decisions. We have also argued the importance of controlling which constraints to apply, when to apply them, and what responses to take on constraint failure in order to make this guidance effective. Our suggestion, to control t...

Compatibility between items, such as clothes and shoes, is a major factor among customer’s purchasing decisions. However, learning “compatibility” is challenging due to (1) broader notions of compatibility than those of similarity, (2) the asymmetric nature of compatibility, and (3) only a small set of compatible and incompatible items are observed. We propose an end-to-end trainable system to ...
