Examine autism in a particular cultural (or ethnic) context: What are the prevalence rates? What are the barriers to diagnosis and care? What treatments/interventions have been tested in this context?

Sample Answer

Autism can be described as a stern development disorder that gravely impairs development and interfears with the ability of speech. It can also refer to wide spectrum of conditions that are characterized by challenges of with social skills, nonverbal communication, repetitive behavior and speech. One of the most known cause of autism is prenatal viral infections

Remote sensor arrange (WSN) for the most part comprise of an increasingly number of vitality obliged sensor hubs with confined on board battery assets which are difficult to energize or supplant. Conventions for WSN are in this manner required to be vitality productive. Multi Input Multi Output (MIMO) frameworks[1] are examined seriously as of late because of their capability to drastically expand the information rate and reduce transmission vitality in remote debilitated channels.

Helpful MIMO structure are made arrangements for WSNs to improve correspondence execution in [2]. In the agreeable MIMO frameworks, various single-recieving wire hubs coordinate on message transmission and gathering for vitality productive interchanges. Where as helpful MIMO can improve the presentation of WSN, the circulated activity of sensors could be an enormous snag to achieve the agreeable transmissions and gatherings. The vitality and time spent in setting up the synergistic transmissions may decrease the presentation increases of MIMO activity if the MAC convention is wastefully structured.

Current point to point correspondences utilize two significant sorts of MAC conventions: conflict based and crash free. In WSNs, the preeminent normal conflict based MAC convention is SMAC [4].The rest state is utilized to diminish the vitality utilization. For the crash free MACs, the LEACH configuration is wide utilized [5]. Lower vitality utilization can be additionally accomplished by utilizing rest periods when the intra-bunch information transmission [5].it can't organize agreeable transmissions of the comparative information from different hubs. Bunching designs, for example, LEACH may likewise be stretched out for the helpful MIMO activity in [7].

The primary capacity of MAC conventions is to plan transmissions from stations sharing the comparable channel and maintain a strategic distance from crashes. medium access control (MAC) conventions for WSN, as a result of vitality imperatives, likewise need to think about vitality effectiveness. Lion's share of the current MAC conventions for WSN use rest wake cycles to decrease the vitality utilization because of inert tuning in remote hubs might be a significant wellspring of vitality wastage [9].

The MAC convention's activity is isolated into adjusts. A round starts with the between bunch length where group heads exchange data with elective bunch heads or with the sink, and leaf hubs may turned off their radios. It is trailed by the intra group period where bunch heads trading data with their leaf hubs.
