The present paper investigates the characteristics and best construction strategies of smart cities around the world, as well as the determining factors of the satisfaction of the quality of life and the importance of the value of environmental sustainability. A case study of the city of Kalampaka and its residents was examined. The survey was conducted between July 2016 and August 2016. The selection of the sample was done by using the method of simple selection and includes a random sample of N=150 individuals. Statistical analysis showed that resident’s knowledge about smart cities was fairly good (48% of sample knew the phrase “smart cities”). Furthermore, they believe that the appearance of the city of Kalampaka needs improvement (75% of sample is disappointed with the current appearance of the city). Regression analysis showed that the value of environmental sustainability is greatly influenced by the energy saving, as well as, innovation has an impact on the level of quality of life. Older people seem to be satisfied with administration’s efforts.

Abstract With the continuous development of blockchain technology and the emergence of application scenarios, consensus algorithms are still the bottleneck restricting the number of network nodes and data writing efficiency that blockchain can support. How to improve the performance of alliance blockchains safely and efficiently has become an urgent problem to be solved at present. For the practical Byzantine fault tolerance algorithm (PBFT) commonly used in alliance blockchains, there are some problems, such as large communication overhead, simple selection of master nodes, and inability to expand and exit nodes dynamically in the network. This paper proposes an improved algorithm tPBFT (trust-based practical Byzantine algorithm), which is suitable for the high-frequency transaction scenario of alliance chains and introduces a trust interest scoring mechanism between network nodes to adjust the list of consensus nodes dynamically, simplify the PBFT consensus process and reduce the interaction overhead between network nodes. Theoretical analysis and experiments show that the improved tPBFT algorithm can effectively reduce the amount of information interaction between nodes, improve consensus efficiency and support more network nodes.

This paper presents the results of a formal experiment to compare different interaction techniques across two types of immersive display: an immersive projection technology (IPT) and a head-mounted display (HMD). Our aim is to investigate the effectiveness of two widely used interaction metaphors, virtual hand and ray casting, on these two display technologies. Our motivation is that design and evaluation of interaction techniques for immersive egocentric display systems has been undertaken almost exclusively on HMDs. We argue that basing interaction for IPTs on techniques developed for other types of immersive systems is a flawed approach, as there are some categorical differences between the experience given by an IPT and an HMD. For example, an IPT user has a much wider field of view than an HMD user. We have chosen two types of interaction tasks to study: simple selection of objects both near to and at some distance from the user, and manipulation of objects involving a change of both position and orientation. As previous studies have found, we find that ray casting is preferable for selection and virtual hand is preferable for manipulation for a HMD. We show that this is also the case for the IPT. More interestingly, while we find performance on selection tasks is much better on the IPT, for manipulation tasks there is little difference between the two display technologies.

AbstractThis paper is devoted to selecting rules for one-dimensional (1D) totalistic cellular automaton (TCA). These rules are used for the generation of pseudorandom sequences, which could be useful in cryptography. The power of pseudorandom number generator (PRNG) based on nonuniform TCA can be improved using not only one rule but a large set of rules. For this purpose, each subset of rules should be analyzed with its assignation to cellular automaton (CA) cells should be analyzed. We examine each of the subsets of totalistic rules, consisting of rules with neighborhood radius equal to 1 and 2. The entropy of bitstreams generated by the nonuniform TCA points out the best set of rules appropriate for the TCA-based generator. The paper also presents the method of simple selection of CA rules based on a cryptographic criterion known as a balance. The proposed method selects a maximal size of the set of available CA rules for a given neighborhood radius and suitable for PRNG. The method guarantees to avoid conflicting assignments of rules resulting in the creation of unwanted stable bit sequences, and provides high-quality pseudorandom sequences. This technique is used to verify the subsets of rules selected experimentally. Verified rules are proposed for 1D TCA-based PRNG as a new subset of best nonuniform TCA rules. New picked, examined, and verified subset of rules could be used in TCA-based PRNG and provide cryptographically strong bit sequences and huge keyspace.

The community service program (CSP) aims to: (1). Increase productivity of Kerinci ducks which are germplasm by utilizing the potential of food crops (rice bran) and plantation waste (palm kernel meal) which can be used as Kerinci duck feed resources with biotricho technology, (2).  Increase Kerinci ducks population using breeding center technology with simple selection and hatching machines. The CSP activity was carried out by the method of active interaction between the implementers  and the target groups involved in this activity, namely: Keluarga Damai and Maju Jaya Mandiri Farmers Group in Tanjung Harapan Village, Kerinci Regency. Some of the implemented programs are: (1). Conseling and training, including: biotricho technology, breeding center technology, utilizing potential local feed stuffs, duck rations, duck selection, and hatching machines, (2). Practicing directly the application of biotricho technology to make formulation of local feed stuffs and breeding center technology with hatching machine technology and simple selection of Kerinci ducks at the Farmer Group level. The results of the activity indicated that the CSP program can be implemented and responded well by the Farmers Group in Tanjung Harapan Village, Kerinci Regency and the implementation of the CSP program is very beneficial for farmers, and Implementing Institutions because it can be a medium to transfer Knowledge and Technology especially the local Kerinci duck which is not done much yet and is not focused. Therefore, the results of studies and the efforts to develop local Kerinci ducks in the countryside are not optimal.

Biomaterials dominate the field of cardiovascular therapeutics, a multitude of which have been used to repair and replace injured heart tissue. This field has evolved beyond the simple selection of compatible materials and now focuses on the rational design of controlled structures that integrate with the cardiovascular system. However, the compatibility of these materials with the blood presents a major limitation to their clinical application. In this context, surface modification strategies can enhance blood compatibility and several recent advances in this area have emerged. This review summarizes the recent applications of biomaterials in cardiovascular therapies, the improvements in their biocompatibility and the surface modification technologies that have the potential to improve clinical outcomes.

Abstract Some of the foundations of Heyes’ radical reasoning seem to be based on a fractional selection of available evidence. Using an ethological perspective, we argue against Heyes’ rapid dismissal of innate cognitive instincts. Heyes’ use of fMRI studies of literacy to claim that culture assembles pieces of mental technology seems an example of incorrect reverse inferences and overlap theories pervasive in cognitive neuroscience.
