Opis:
The paper is a survey devoted to job scheduling problems with resource allocation. We present the results available in the scientific literature for commonly used models of job processing times and job release dates, i.e., the models in which the job processing time or the job release date is given as a linear or convex function dependent on the amount of the additional resource allotted to the job. The scheduling models with resource dependent processing times or resource dependent release dates extend the classical scheduling models to reflect more precisely scheduling problems that appear in real life. Thus, in this paper we present the computational complexity results and solution algorithms that have been developed for this kind of problems.

Opis:
In the paper, we consider a problem of scheduling a set of tasks on a single processor. Each task must be preprocessed before it can be started on a processor. The efficiency of preprocessing is variable, i.e., the rate of the task preprocessing depends on the amount of continuously divisible resource allotted to this task. This dependency is given by concave, continuous, non-negative and strictly increasing function of the resource amount. The total consumption of resource at each moment is upper bounded. The objective is to minimize the maximum task completion time. The considered problem is NP-hard. Such a problem appears, e.g., in steel mill systems, where ingots (before hot rolling on the blooming mill) have to achieve the required temperature in the preheating process in soaking pits. Some new properties of the problem are proved. These properties are used to construct the procedure for evaluation of the neighbourhood. The procedure is proposed to improve the efficiency of algorithms based on the neighbourhood concept, such as metaheuristics. The computational experiment is conducted to examine the efficiency of the proposed procedure. The described approach can be easily used in the other discrete-continuous scheduling problems.

Opis:
A fully polynomial time approximation scheme (FPTAS) with run time 0(nm/ εm-1) is developed for a problem which combines common due window assignment and scheduling n jobs on m identical parallel machines. The problem criterion is bottleneck (min-max) such that the maximum cost, which includes job earliness, job tardiness and due window size costs, is minimized.

Opis:
B6C3F₁ mice were infected with 200 or 500 larvae of Trichinella spiralis per mouse and pulmonary NK cell-mediated clearance of semisyngeneic tumour cells was determined in vivo on days 10, 20, 30, and 60 after the infection. Cytotoxic activity of NK cells in the lungs was substantially elevated on days 20 and 30 after challenge with both „doses" of the parasite. At the same time large granular lymphocytes (LGLs) as well as cells expressing surface asialo-GM₁ molecules were isolated in elevated numbers from spleens of the infected as opposed to the normal mice. Expression of other markers of differentiation, such as THy 1, CD4, and CD8 was also enhanced on splenocytes isolated from the infected mice on day 30 but not 20 after administration of the larvae. The present results indicate that NK cell-mediated activity in vivo is stimulated above the baseline level during migration and early muscle phases of the infection with T. spiralis in mice. The possible impact of this effect upon the course of trichinellosis as well as upon the growth of tumours in the infected host is discussed.

Opis:
This article presents a robot for remote noninvasive medical examination. In particular, this robot allows a doctor to carry out an interview, an observation, an auscultation and an ultrasound examination, including echocardiography. The robot has been developed within the ReMeDi (Remote Medical Diagnostician) project funded by the European Union’s Research and Innovation 7th Framework Programme. At the beginning of the article, we outline selected results of the user’s evaluation of the robot idea together with the requirements regarding the robot. Then the essential system components are presented and a selection of them are discussed in detail. Subsequently we present the integrated system and discuss selected topics concerning the integration. Finally, the document is completed by a description of the users evaluation process.
