لیستریا مونوسایتوژنز یک پاتوژن غذایی مهم و عامل لیستریوزیس در انسان و حیوان است. از آنجاکه این باکتری می تواند شرایط سخت محیطی را تحمل نماید، به عنوان یک تهدید مهم در صنایع غذایی مطرح است. شیوع گاه به گاه لیستریوزیس به خصوص در اثر مصرف لبنیات در سال های اخیر سبب شده است که شناسایی و تشخیص آلودگی مواد غذایی به این باکتری مورد توجه قرار گیرد. در مطالعه حاضر دو روش mpn-pcr و real-time pcr با هدف ک...
Tele-immersion is a new medium that enables a user to share a virtual space with remote participants, by creating the illusion that users at geographically dispersed locations reside at the same physical space. A person is immersed in a remote world, whose 3D representation is acquired remotely, then transmitted and displayed in the viewer’s environment. Tele-immersion is effective only when th...
In this paper, we consider multiprocessor implementation of real-time recursive digital signal processing algorithms. The objective is to devise a periodic schedule, and a fully static task assignment scheme to meet the desired throughput rate while minimizing the number of processors. Toward this goal, we propose a notion called cutofs time. We prove that the minimumprocessor schedule can be f...
To appear in Information Systems real-time database system is a database system in which transactions have explicit timing constraints such as deadlines. Apart from satisfying the database consistency constraints, transaction executions must also satisfy these timing constraints. The goal of transaction and query processing in real-time databases is to maximise the number of successful transact...
In this paper the real time virtual dress-up system has been proposed. The proposed system consists of multiple tasks including extraction of different body parts, torso detection, resizing input dress images and dress up using blending and re-blending techniques over the subject. The coexistence of different clothing and cluttering backgrounds is the main difficulty for accurate body extractio...
A real-time implementation of a 2.4 Kbps mixed excitation linear prediction (MELP) speech-coding algorithm on a 20 MIPS TMS320C44 digital signal processor is described. The main emphases of the paper are on efficient coding and optimization strategies in computationally intensive modules by exploiting fast memories and registers of the C44 instruction set. Although the implementation is based o...
This paper describes ongoing work on the automatic construction of formal models from Real-Time implementations. The model construction is based on measurements of the timed behavior of the threads of an implementation, their causal interaction patterns and external visible events. A specification of the timed behavior is modeled in timed automata and checked against the generated model in orde...
The use of transputer family microprocessors in hard real-time control applications is studied. The transputer offers computing performance and architectural features like support of process scheduling and multiprocessing on hardware and language level. Some of these features are efficient for real-time systems, but some contradict with the system performance. Occam process structure is matched...
This work presents an analytic solution to a 2-D waveguide mesh, made square with input and output at the center to produce a symmetry that reduces redundancy and increases computational savings. The result is a frequency-domain representation of the mesh, a parametric transfer function describing the ratio of output to input, symbolically computed to retain parameters. In this form, the mesh, ...
