The Euler characteristic of an enriched category
We define Euler characteristic of a category enriched by a monoidal model
category. If a monoidal model category V is equipped with Euler characteristic
that is compatible with weak equivalences and fibrations in V, then our Euler
characteristic is also compatible with weak equivalences and fibrations in the
model structure induced by that of V. In particular, we focus on the case of
topological categories; that is, categories enriched by the category of
topological spaces. As its application, we obtain the ordinary Euler
characteristic of a cellular stratified space X by computing the Euler
characteristic of the face category C(X) induced from X
BENEFITS OF USING SOFTWARE WITH SIK COMPLIANT ARCHITECTURE IN CLOUD
The aim of this paper is to investigate the main benefits that can be obtained by using a SIK (software inherited knowledge) compliant architecture for cloud services and support software used to build, administer and maintaining the cloud. It introduces the basic building blocks for cloud computing together with the main categories of cloud services. For the SIK architecture, shown in connection with a semantic-web application architecture, are introduced the main functionalities. The paper outlines then the main benefits different categories of users may have from both cloud and SIK compliant architecture for the cloud services delivered onto, for extensive knowledge management, and for creating the base for semantic-web for the modeled domain, the software oeration and usage, and automated administrative tasks for the cloud.software inherited knowledge, SIK, cloud-computing, knowledge management
Considerations in Designing Human-Computer Interfaces for Elderly People
As computing devices continue to become more heavily integrated into our lives, proper design of human-computer interfaces becomes a more important topic of discussion. Efficient and useful human-computer interfaces need to take into account the abilities of the humans who will be using such interfaces, and adapt to difficulties that different users may face – such as the difficulties that elderly users must deal with. Interfaces that allow for user-specific customization, while taking into account the multiple difficulties that older users might face, can assist the elderly in properly using these newer computing devices, and in doing so possibly achieving a better quality of life through the advanced technological support that these devices offer. In this paper, we explore common problems the elderly face when using computing devices and solutions developed for these problems. Difficulties ultimately fall into several categories: cognition, auditory, haptic, visual, and motor-based troubles. We also present an idea for a new adaptive operating system with advanced customizations that would simplify computing for older users
Definition and Categorization of Dew Computing
Dew computing is an emerging new research area and has great potentials in applications. In this paper, we propose a revised definition of dew computing. The new definition is: Dew computing is an on-premises computer software-hardware organization paradigm in the cloud computing environment where the on-premises computer provides functionality that is independent of cloud services and is also collaborative with cloud services. The goal of dew computing is to fully realize the potentials of on-premises computers and cloud services. This definition emphasizes two key features of dew computing: independence and collaboration. Furthermore, we propose a group of dew computing categories. These categories may inspire new applications
