  • Maintaining landscape connectivity through identifying movement corridors is the most recommended conservation strategy to reduce the negative impacts of habitat loss and isolation. The basis of most connectivity modelling approaches for modelling corridors is that species choose movement pathways based on the same criteria they used to choose habitats. However, species behave differently in using landscape elements for moving than for selecting habitat. In other words, suitability of a given landscape feature may differ between moving and habitat use stages.

  • To achieve global food security, rising agricultural productivity through modern breeding strategies is of prime interest. A variety of biotic and abiotic stresses influences both productivity and crop quality, and it is essential for growing crops with improved adaptability, high productivity and resistance to these biotic/abiotic stresses. Availability of genome sequences helps to improve crop production by using different biotechnological tools.

  • In previous lecture we explored the limitations of the centralized key distribution and have explored key distribution in a decentralized fashion. We discussed in detail, how message authentication could be achieved. There are several functions and protocols used for message authentication. This chapter you would be able to present an understanding of the higher level message authentication mechanism, demonstrate knowledge about different protocols used for message authentication.

  • The purpose of this paper is to employ the Meta-Frontier Cost Function to compare the bank efficiencies in Indonesia, Malaysia, and Thailand during the period of 2002–2009. We propose two new variables: income on loans and non-performing loans, to identify whether the banks are both cost and profit efficient and to control the quality of loans in contrast with early studies using loans and securities as the output variables. Evidence is found that the Indonesian banks are the most efficient. The empirical results illuminate the governments’ policies and bank management.

  • The paper presents a novel technique to detect Denial of Service (DoS) attacks applied by misbehaving nodes in wireless networks with the presence of hidden nodes employing the widely used IEEE 802.11 Distributed Coordination Function (DCF) protocols described in the IEEE standard [1]. Attacker nodes alter the IEEE 802.11 DCF firmware to illicitly capture the channel via elevating the probability of the average number of packets transmitted successfully using up the bandwidth share of the innocent nodes that follow the protocol standards.

  • The optimization of a novel programmable data-flow crypto processor dedicated to security applications is considered. An architecture based on assigning basic functional units to four synchronous regions was proposed in a previous work. In this paper, the problem of selecting the number of synchronous regions and the distribution of functional units among these regions is formulated as a combinatorial multi-objective optimization problem. The objective functions are chosen as: the implementation area, the execution delay, and the consumed energy when running the well-known AES algorithm.
