Surveillance

 

مقدمه :

  از آنجا که طی طغیان‌ها و همه‌گیری‌های مرتبط با بیوتروریسم، معمولا فرصت کافی برای اثبات عوامل سببی و تشخیص قطعی (Confirmed) وجود ندارد ، لــذا با بهره‌گیری از مراقبت (Surveillance) و رویاروئــی  (Approach) با نشانگان بالینی (Syndromes) و استفاده از اقدامات پاراکلینیکیِ با پاسخ دهی سریع نظیر انواع رنگ‌آمیزی، تست‌های سرولوژیک آنتی‌ژنی، PCR ELISA, . . . و تصویر برداری‌های مختلف، به تشخیص‌های محتمل(Probable) می‌پردازیم و بر آن اساس، اقدامات درمانی و اپیدمیولوژیک لازم را آغاز می‌کنیم0  به عبارت دیگر در سیستم مراقبت سنّتی، معمولا به پیگیــری بیماری‌هــا پرداخته می‌شود در حالیکــه در سیستم مراقبت سندرومیک، اطلاعات مربوط به علائم و نشانه‌های موجود در بیماران، جمع‌آوری و پس از قراردادن مجموعه‌ای از آن‌ها در قالب‌های تعریف شده قبلی (نشانگان = سندروم) به تشخیص‌های محتمل و زودرس، دست می‌یابیم.  

 

 

 

 

Objectives :

•Early detection of possible events essential

•Most bioterrorism agents cause diseases that are rapidly fatal

•May be treatable in early stages or preventable with antibiotics,vaccination, or anti-sera

•If person-to-person transmission, early intervention may be best disease     prevention strategy

(Collects information about patients’ signs and symptoms)

اهداف مراقبت و رویاروئی سندرومیک

• کشف سریع حوادث بیوتروریستی
• درمان به موقع بیماری‌هائی که سریعا منجر به مرگ می‌شوند
• انجام اقدامات پیشگیرنده، در تماس‌یافتگان بدون علائم بالینی (پیشگیری داروئی، واکسیناسیون، سرم‌درمانی و . . . )
• قطع زنجیره انتقال در بیماری‌های واجد حملات ثانویه

üIn order to develop more efficient engines, it is essential to optimize the lubrication circuit of the power train systems.

üTwo elements have been added to the lubrication circuit in the modified engine. These elements are hydraulic lifters and an Anti-drain valve.

The analyses are done by Flowmaster7.6 and AVL EXCITE7.02 software and an accessory code.

 Finally, theoretical results are validated by a completely controlled lubrication functional test.

Modern engines are being designed to operate at high engine speeds and loads. In order to fulfill the requirements of developing new engines, lubrication system must be improved.

Yiqing Yuan et al, in 2007, established a methodology for predicting lubrication flow in the rod bearings and oil circuits that can be used to guide engineering designs.

Yaguo Lu et al. [10], in 2009, developed a software for simulating aero-engine lubrication system.

In this paper, two important components, chain tensioner and anti-drain valve, have been investigated as well as other components in the lubrication system.

Engine description

There are three important reasons for improving the base engine to the modified engine:

(1) using inexpensive and locally abundant CNG fuel,

(2) demanding higher power and

(3) modifying weaknesses of the base engine. The engine parameters are listed in table.

Lubrication functional test

This test is applicable to Diesel and Gasoline engines.

After installing the sensors in particular locations of lubrication circuit like the main gallery, oil pump outlet, oil filter inlet and outlet, the end side of the hydraulic lifter gallery, the engine is configured on the dynamometer and prepared for lubrication functional test. This test is divided into steady state and transient parts.

A Game-theoretic Approach to Security and Power Conservation in Wireless Sensor Networks

Abstract
In this paper, we investigate the impacts of applying game
theory on the network throughput, network voltage loss
and accuracy of malicious node detection to wireless sen-
sor networks. We implement a protocol which the sensors
use when deciding whether or not to forward packets they
receive from other sensors in order to conserve power.
Nodes in a wireless sensor network accomplish this by
optimizing their decision making based on a framework
using game theory. De¯ning a suitable cost and pro¯t to
routing and forwarding incoming packets and keeping a
history of experiences with non-cooperating nodes drives
malicious nodes out of the wireless sensor network.

Abstract— A Wireless Sensor Network (WSN) is a collection of
wireless sensor nodes forming a temporary network without
the aid of any established infrastructure or centralized
administration. In such an environment, due to the limited
range of each node’s wireless transmissions, it may be
necessary for one sensor node to ask for the aid of other sensor
nodes in forwarding a packet to its destination, usually the
base station. One important issue when designing wireless
sensor network is the routing protocol that makes the best use
of the severely limited resource presented by WSN, especially
the energy limitation. Another important factor is providing as
much security to the application as possible. In this project, an
energy efficient secure node disjoint multipath routing
protocol for wireless sensor networks is proposed. Here, the
data packets are transmitted in a secure manner by using the
digital signature crypto system. Multipath routing protocols
enhance the lifetime of the wireless sensor networks by
distributing traffic among multiple paths instead of a single
optimal path. The protocol guarantees loop freedom and
disjointness of alternate path. We have compared the
performance of this protocol with an ad hoc on-demand
multipath distance vector routing protocol. To evaluate
performance of proposed method, we have used parameters
packet delivery ratio, energy consumption, routing overhead
and throughput compare to the ad hoc on-demand multipath
distance vector routing .
