Despite the advantages of shrinking transistors’ dimensions, e.g. decrease in power consumption and fabrication cost and increase in their switching speed, it has an adverse impact on some characteristics of nano-scale (less than 130nm) transistors that can reduce the system lifetime. Bias Temperature Instability (BTI) and Hot Carrier Injection (HCI) are amongst the most important adverse effects of transistor shrinkage. These two effects, are known as transistor aging, decrease the switching speed of the transistors by increasing the threshold voltage and decreasing the charge carriers’ mobility in the channel of transistors. Temperature, operating voltage, and the size of transistors have... 

Consumers make buying decisions every day and managers or marketers try to understand why, when, where and how consumers make decisions to buy a product. One complex duty of managers is to understand consumer buying behavior in order to adapt their effort to consumers’ interest. Many studies gathered possible influent factors on consumer buying decisions that should consider as a basic of marketing strategy effort. In this time due to appearance large competitors and producers in the market of home appliance in Iran, consumers have more choice to select and purchase one product among different brands. In addition, high volume of advertizing, consistency of preliminary attribute among... 

Environmental problems have been one of the considerable issues since the irreversible characteristics of nature and its effect on human life were recognized. Scientists have proposed a variety of solutions in order to overcome such problems. Green marketing can be regarded as one of the solutions in this area. Similar to most other issues, this concept has been noticed less in developing countries compared to developed countries. Therefore, researchers in this study conducted a comprehensive research on the concept of green marketing in Iran focusing on consumers’ behavior.
To achieve relevant results, two types of research were conducted: qualitative and quantitative. The results of... 

Traditionally, Iran was looking for development and either in era of oil revenues or before that, it has always faced serious mismatches in realization of plans and indiscipline of definition, allocation of development budgets, and sometimes national and foreign borrowing and in spite of defining development plans from 1971s, today, rare plans have been achieved in an acceptable and defendable manner, meanwhile, Iran’s Islamic Revolution adopted some fact changes in defining concepts like entrepreneurs, wealth, and the government’s share. However, many politicians and environmental activists are seeking sustainable development; environmental campaigners believe that this option is not...

Growth in the number of transistors on a single die has made Network-on-Chips more vulnerable to transient faults such as Crosstalks, SEUs and MBUs. The aim of this thesis is to evaluate the effects of virtual channel structures on the performance and the power consumptions of NoCs in the presence of transient faults. Evaluations have been carried out by different switch architectures and experimental conditions, i.e., different traffic and fault injection rates. In this regard, we have measured the power and latency of the switch both in different buffer allocation mechanisms and different switching methods. The evaluated switching methods in this work vary from Virtual Cut through (VCT) to...

The wide range of embedded processors and their reliance on nano-scale technologyhave brought them serious concerns on reliability, power consumption, timeliness and cost. Therefore, theseconcernsmust be addressed at the design process withemploying minimum facilities.This thesis proposes a low-cost concurrent error detection method based on control flow checking suitable for embedded processors. Most of the previous control flow checking methods either do not consider the embedded processors concerns, or they are not applicable to processors with on-chip cache memories.The key idea behind the proposed control flow checking method is to embed specific hardware components in the IP core of an... 

Energy consumption, area, reliability and predictability are the major concerns in embedded systems. Using scratchpad memories (SPMs) instead of cache memories has an increasing role to satisfy these limitations. SPM as an on-chip SRAM memory is highly vulnerable to soft errors and as it contains the most frequently used blocks of the program, errors in SPM can easily propagate in system leading to erroneous results. This thesis proposes two approaches to protect the SPM against soft errors. The first approach, MM-SPM, proposed to protect the instruction SPM and the second approach, CR-SPM, proposed to protect dynamically mapped data and instructions to the SPM. The main idea behind the... 

In recent years, the use of embedded processors has grown increasingly in wide range of computer systems; so that most of manufactured CPUs are used in emebedded systems many of which are safty-critical systems such as medical devices, aircraft flight control, space systems, nuclear systems, etc. The incidence of failure in these systems can cause irreversible damages on human life, financial or environmental matters. Silicon process technology trends, such as reducing the threshold voltage, increasing the frequency and decreasing the size of transistors, not only caused increase in single-bit fault rate but also caused occurance of multi-bit faults. Due to importance ofcorrect operation of... 

Nowadays, one of the most important challenges in the design of digital circuits is their susceptibility to the strike of high energy particles which leads to the Single Event Transient (SET) and Multiple Event Transients (MET). In fact, technology scaling which results in lower supply voltage, higher operating frequency, and lower nodal capacitance, makes today’s digital circuits more susceptible not only to high energy particles but also to low energy particles. Moreover emerging deep sub-micron technologies and the integration of more cells in today’s chips have caused higher probability of MET occurrences. A lot of research has tried to reduce the soft error rate due to high energy... 

Wireless Sensor Networks (WSNs) are prone to faults due to battery depletion of nodes, where a node failure can disturb routing, as it plays a key role in transferring sensed data to the end users. A WSN may be partitioned into groups of nodes called clusters; for every cluster, there is a node, called Cluster Head (CH) that is responsible for collecting and transferring data from all nodes in that cluster. This means that the CH is a single point of failure; i.e., once a CH fails, the whole cluster will fail, which leads to inability of its members for transferring data outside the cluster. This thesis presents a Fault-Tolerant and Energy-Aware algorithm (FTEA), which prolongs the lifetime...
