A study is conducted to examine the antibacterial activities of the emulsions containing essential oil of Beakea Frustescence. The emulsions were formulated according to the information obtained from the constructed phase equilibriums consisting water, SDS, Span 80 and hexane. Followed by the preparation was a stability test, which was carried out within the following three weeks to determine t...

In this paper we present a case study in the industry about the application of a test case generation method based on B machine specifications. First we describe the step-by-step process of the test case generation method and then we present its use in a particular case study for door controlling module from a subway system. Lastly, we discuss the results obtained after this study and the futur...

Our general purpose was to determine whether arthropod communities in midsuccessional habitat are qualitatively different from those in mature habitat. Specifically, we investigated whether foraging guild structure, abundance, and diversity differ in relation to fire history and whether there is evidence of failure in community recovery after a fire. Lastly, we compared our results for the enti...

We study a two-sided singular control problem in a general linear diffusion setting and provide a set of conditions under which an optimal control exists uniquely and is of singular control type. Moreover, under these conditions the associated value function can be written in a quasi-explicit form. Furthermore, we investigate comparative static properties of the solution with respect to the vol...

We present a precis-of an approach to relevance as it pertains to weak conditionMs and defeasible reasoning. The notion of relevance is taken as a relation between a property (such as, being green) and a conditional (such as, birds fly). A series of principles characterising a minimal, parsimonious notion of relevance is developed. Lastly, an explicit definition that agrees with the postulates ...

In this paper, we establish bounds on the norm of multiplication operators on the Bloch space of the unit disk via weighted composition operators. In doing so, we characterize the isometric multiplication operators to be precisely those induced by constant functions of modulus 1. We then describe the spectrum of the multiplication operators in terms of the range of the symbol. Lastly, we identi...

This paper firstly introduces the characteristics of PostScript document and PDF document as the basis, and proposes the necessity and the feasibility of the conversion from the PDF document format to the PostScript language program. Secondly, it studies the main algorithm and technology of the conversion process and realizes the information extraction for PDF document lastly, with achieving th...

This paper reviews tactual perception of material properties such as roughness, compliance, coldness and friction. Psychophysical functions relating physical properties to perception are discussed, as well as discrimination thresholds. Also, the neural codes mediating some of these sensations are discussed. Furthermore, we take a look into how sensation of these material properties can be induc...

The problem is convex quadratic and a stationary point is necessary and sufficient for global optimality. The following sections will discuss how Problem 1 is solved in the primal domain, dual domain, and for both single and multiple templates along with the formula used to generate the response map, whose maximum value determines the current detection. Lastly, we discuss a one way of incorpora...

In this paper we present results from an exploratory qualitative study on the family communication practices of family members in Kenya. We reveal that family communication focuses on economic support, well-being, life advice, and everyday coordination of activities. Lastly, we discuss new opportunities for technology design and articulate the challenges that designers will face if creating or ...
