The control engineering group at the University of Twente creates control applications for embedded systems among others. In order to create such applications, graphical modelling tools such as 20-sim and gCSP are used to generate software for various platforms. Currently, the output of these code generating programs is ANSI C code, which rules out the use of FPGA's as a target. FPGA devices of...

machines and process calculi The first model to capture the complex interplay between non-determinism and concurrency in distributed systems was Petri Nets [Pet], these nets were designed information flow in natural as well as man-made systems. In the early eighties, algebraic process calculi [BHR][Mil] were designed to model interactive systems hierarchically, and to model their behaviour abst...

In this paper, we present the design optimization of oneand two-dimensional fullypipelined computing structures for area-delaypower-efficient implementation of finite impulse response (FIR) filter by systolic decomposition of distributed arithmetic (DA)based inner-product computation. The systolic decomposition scheme is found to offer a flexible choice of the address length of the lookup-table...

Elmi-texniki tərəqqi əsrində bitkilərin kimyəvi tərkibinin öyrənilməsi, hər bir biokimyəvi maddənin insan və heyvan orqanizminə təsiri, onlardan müxtəlif dərman formalarının preparatların hazırlanması ən aktual məsələlərdən biri olmuşdur. Məsələnin aktuallığı ondadır ki, bu sahədə çox elmi-tədqiqat işləri yerinə yetirilsədə, hələ də araşdırmalar tamamlanmamışdır. Məlum olduğu kimi, hazırda prep...

In the current Shenzhen Code (Turland & al. in Regnum Veg. 159. 2018), one might infer from last sentence of Art. H.6.2, which covers nothogeneric names bigeneric hybrids that are condensed formulas (“The use a hyphen instead or addition to connecting vowel is treated as an error be corrected by deletion hyphen.”), this rule applies only hybrids. When sentence, was new Code, originally proposed...

A Mahommedan boy of about 14 years of a"-e was brought to me on August 20th, 1922, suffering from general peritonitis, probably of appendicular origin, and practically moribund. I opened one internal saphenous vein in front of the ankle and ran in 1^ pint of saline-glucose and brandy and adrenalin whilst getting ready for operation. Under local analgesia I opened above the pubes and put a large...

The Hough transform (HT) is frequently used to locate possibly occluded straight edges or lines in machine vision. Each detected edge pixel in a binary image votes for a potential edge upon which it might lie. The HT is potentially suitable for video-rate applications such as motion detection (by comparison of successive HT transformed frames), but the computational burden is high, motivating h...

The ATLAS second level trigger will use a multi-layered LAN network to transfer 5 Gbyte/s detector data from ~1500 buffers to a few hundred processors. A model of the network has been constructed to evaluate its performance. A key component of the network model is a model of an individual switch, reproducing the behavior measured in real devices. A small number of measurable parameters are used...

In this dissertation, we discuss the design of a reconfigurable, unified HMAC-hash unit for IPSec authentication. The proposed unit is reconfigurable at runtime to enable implementing any of six standard algorithms: MD5, SHA-1, RIPEMD-160, HMAC-MD5, HMAC-SHA-1, and HMAC-RIPEMD-160. The designed unit can be used for IPSec or any other security application that uses hash functions, such as digita...
