The concept of a miniature transmission electron microscope (TEM) on chip is presented. This idea assumes manufacturing of a silicon-glass multilayer device that contains a miniature electron gun, an electron optics column integrated with a high vacuum micropump, and a sample microchamber with a detector. In this article the field emission cathode, utilizing carbon nanotubes (CNT), and an electron...
In this paper we present for the first time inkjet 3D printed lab-on-a-chip for DNA analyse by on-chip gel electrophoresis. Separation of 50÷800bp DNA ladder was successfully performed. According to our best knowledge it is the first example of such application of 3D printed microfluidics structure. Thanks to advantages of 3D printing it is possible to develop lab-on-a-chip with user defined configuration...
In Statistical Process Control (SPC) there exists a need to model the run-length distribution of a Q-chart that monitors the process mean when measurements are from an exponential distribution with an unknown parameter. To develop exact expressions for the probabilities of run-lengths the joint distribution of the charting statistics is needed. This gives rise to a new distribution that can be regarded...
This paper is devoted to the application of an Evolutionary Algorithm to the design of Finite Impulse Response filters (FIR). A hybrid algorithm is proposed, which consists of a robust global optimization method (Evolutionary Algorithm - EA) and a good local optimization method (Quasi-Newton - QN). An experimental comparison of the hybrid algorithm against EA and QN alone indicates that EA yields...
In this paper we analyze the filter design task and interprete it as an optimization problem. We verify the possibility of applying good local optimization method (quasi-Newton - QN) and a robust global optimization method (evolutionary algorithm - EA). According to the results of the computer simulation, we conclude that a hybrid solution that combines these two method yields filters of the amplitude...

In this paper we study the genotype diversity of the base population. We provide evidence that the diversity is closely related to the genealogy of individuals and to the degree of mutation. We give analytical formulas for the diversity distribution in the space of binary and real vectors. The theoretical results are supported by numerical experiments.

Opisano ruchomy system radarowy ARTHUR lokalizujący broń artyleryjską, opracowany przez firmę Ericsson. System jest wykorzystywany do wykrywania i lokalizacji nieprzyjacielskich stanowisk ogniowych podczas strzelania we wszystkich fazach walki oraz do kierowania ogniem artylerii własnej. Dzięki małej masie, małym rozmiarom i zabudowie na pojedynczym pojeździe, wyróżnia się bardzo wysoką mobilnością...
