Embryonic Architecture with Built-in Self-test and GA Evolved Configuration Data

The embryonic architecture, which draws inspirationfrom the biological process of ontogeny, has built-inmechanisms for self-repair. The entire genome is stored in theembryonic cells, allowing the data to be replicated in healthycells in the event of a single cell failure in the embryonic fabric.A specially designed genetic algorithm (GA) is used to evolve theconfiguration information for embryonic cells. Any failed embryoniccell must be indicated via the proposed Built-in Self-test(BIST) the module of the embryonic fabric. This paper recommendsan effective centralized BIST design for a novel embryonic fabric.Every embryonic cell is scanned by the proposed BIST in casethe self-test mode is activated. The centralized BIST design usesless hardware than if it were integrated into each embryoniccell. To reduce the size of the data, the genome or configurationdata of each embryonic cell is decoded using Cartesian GeneticProgramming (CGP). The GA is tested for the 1-bit adder and2-bit comparator circuits that are implemented in the embryoniccell. Fault detection is possible at every function of the cell due tothe BIST module’s design. The CGP format can also offer gate-levelfault detection. Customized GA and BIST are combinedwith the novel embryonic architecture. In the embryonic cell, self-repairis accomplished via data scrubbing for transient errors

Using MapReduce Streaming for Distributed Life Simulation on the Cloud

Distributed software simulations are indispensable in the study of large-scale life models but often require the use of technically complex lower-level distributed computing frameworks, such as MPI. We propose to overcome the complexity challenge by applying the emerging MapReduce (MR) model to distributed life simulations and by running such simulations on the cloud. Technically, we design optimized MR streaming algorithms for discrete and continuous versions of Conway’s life according to a general MR streaming pattern. We chose life because it is simple enough as a testbed for MR’s applicability to a-life simulations and general enough to make our results applicable to various lattice-based a-life models. We implement and empirically evaluate our algorithms’ performance on Amazon’s Elastic MR cloud. Our experiments demonstrate that a single MR optimization technique called strip partitioning can reduce the execution time of continuous life simulations by 64%. To the best of our knowledge, we are the first to propose and evaluate MR streaming algorithms for lattice-based simulations. Our algorithms can serve as prototypes in the development of novel MR simulation algorithms for large-scale lattice-based a-life models.https://digitalcommons.chapman.edu/scs_books/1014/thumbnail.jp

A complex systems approach to education in Switzerland

The insights gained from the study of complex systems in biological, social, and engineered systems enables us not only to observe and understand, but also to actively design systems which will be capable of successfully coping with complex and dynamically changing situations. The methods and mindset required for this approach have been applied to educational systems with their diverse levels of scale and complexity. Based on the general case made by Yaneer Bar-Yam, this paper applies the complex systems approach to the educational system in Switzerland. It confirms that the complex systems approach is valid. Indeed, many recommendations made for the general case have already been implemented in the Swiss education system. To address existing problems and difficulties, further steps are recommended. This paper contributes to the further establishment complex systems approach by shedding light on an area which concerns us all, which is a frequent topic of discussion and dispute among politicians and the public, where billions of dollars have been spent without achieving the desired results, and where it is difficult to directly derive consequences from actions taken. The analysis of the education system's different levels, their complexity and scale will clarify how such a dynamic system should be approached, and how it can be guided towards the desired performance

Senescence

The book "Senescence" is aimed to describe all the phenomena related to aging and senescence of all forms of life on Earth, i.e. plants, animals and the human beings. The book contains 36 carefully reviewed chapters written by different authors, aiming to describe the aging and senescent changes of living creatures, i.e. plants and animals

Plant Physiology, Development and Metabolism

Water is one of the most important constituents of life. Chemically, water is the hydride of oxygen. Oxygen, being more electronegative, exerts a strong attractive pull on its electrons. This unequal attraction results in small positive charge on twohydrogenmoleculesandasmallnegativechargeontheoxygenmolecule.The two lone pairs of electrons of the oxygen molecule result in bending of water molecule. The partial charges on oxygen and hydrogen molecules result in high electric dipole moment and polarity of water molecule
