| Detection methods for multiple rate Direct Sequence Code Division Multiple Access (DS-CDMA) signalling are addressed. Attention is focussed on the development of receivers based on the minimum mean squared error (MMSE). Due to the cyclostationarity of the mul-tirate signal, a representation of the multirate signal in terms of the Fourier basis is possible. This expansion facilitates construct...

An analysis of chipping fracture in brittle solids is presented. Cracks are introduced into the edges of selected materials, including soda-lime glass and fine-grain ceramics, using a Vickers indenter in monotonic loading. The ensuing chip morphology is examined and shown to exhibit a certain geometrical similarity, independent of material properties. A simple universal relation is derived for ...

We investigate an idealized model for the size reduction and smoothing of a polygonal rock due to repeated chipping at corners. Each chip is sufficiently small so that only a single corner and a fraction of its two adjacent sides are cut from the object in a single chipping event. After many chips have been cut away, the resulting shape of the rock is generally anisotropic, with facet lengths a...

We discuss the architecture and design of parallel sampling front ends for analog to information (A2I) converters. As a way of example, we detail the design of a custom 0.5 μm CMOS implementation of a mixed signal parallel sampling encoder architecture. The system consists of configurable parallel analog processing channels, whose output is sampled by traditional analog-to-digital converters (A...

The presented work deals with an analysis of causes the very low service life new version hand woodworking planing knife, which has replaced original a knife. Based on performed experimental works, chemical analysis, macroscopic and microscopic observation, SEM, diffractometric Vickers hardness test it was concluded that cause for (practically nonexistent one) knife are significant features ove...

Nacrtak For sanitary reasons, spruce trees affected by bark beetles (Ips typographus L.) should be removed out of the stand as soon as possible, to avoid the propagation of the beetles to healthy trees. One possibility, to utilize the accruing crown material in a reasonable way (instead of burning it) could be, to use it as wood-chips for biomass heating plants. The aim of this project was ther...

Myeloid neoplasms are clonal diseases of hematopoietic stem or progenitor cells that result from molecular alterations that perturb cellular self-renewal, proliferation, and differentiation. As classified by the World Health Organization, myeloid neoplasms include myeloproliferative neoplasms (MPN), myelodysplastic syndromes (MDS), MPN/MDS overlap, and acute myeloid leukemia (AML), which can oc...

There are numerous recorded reports which manages the corruption of paper because of paper maturing, foundation variety because of clamor, uneven brightening or dim spots and characterization of loss of literary data in debased archives like light introduction which causes blurring of content or ink chipping, Degradation of the written work medium i.e. clouded or missing content brought about b...
