Kinematics, Dynamics, and Optimal Control of Pneumatic Hexapod Robot

Pneumatic hexapod robot is driven by inert gas carried by itself, which has board application prospect in rescue operation of disaster conditions containing flammable gas. Cruising ability is main constraint for practical engineering application which is influenced by kinematics and dynamics character. The matrix operators and pseudospectral method are used to solve dynamics modeling and numerical calculation problem of robot under straight line walking. Kinematics model is numerically solved and relationship of body, joints, and drive cylinders is obtained. With dynamics model and kinematics boundary conditions, the optimal input gas pressure of leg swing and body moving in one step is obtained by pseudospectral method. According to action character of magnetic valve, calculation results of control inputs satisfy engineering design requirements, and cruising ability under finite gas is obtained.
Annual Grass Control in Peanut (Arachis hypogaea) with Clethodim and Imazapic1

Field experiments were conducted to evaluate possible interactions of clethodim with imazapic applied as mixtures or sequentially for control of broadleaf signalgrass, fall panicum, goosegrass, and large crabgrass. Imazapic at 70 g ai/ha alone controlled grass weeds inconsistently, whereas clethodim at 140 g ai/ha alone controlled the same weeds at least 99%. Imazapic did not affect broadleaf signalgrass control by clethodim. Reduced control of fall panicum, goosegrass, and large crabgrass was observed when clethodim and imazapic were applied in mixture. Antagonism of clethodim occurred when clethodim was applied 1 d before or up to 3 d after application of imazapic (fall panicum and large crabgrass). Antagonism of goosegrass control was noted when imazapic was applied 3 d before or up to 7 d after application of clethodim. In other experiments, large crabgrass and Texas panicum control by clethodim (70 and 140 g/ha) applied alone or with imazapic (70 g/ ha) or bentazon (1.1 kg ai/ha) plus 2,4-DB (0.28 kg ai/ha) either with or without ammonium sulfate (2.8 kg/ha) was evaluated. Texas panicum control by clethodim was reduced by imazapic regardless of the ammonium sulfate rate. However, large crabgrass control by imazapic was not affected in these experiments. Control of both grasses by clethodim was reduced substantially by bentazon plus 2,4-DB, although in some instances ammonium sulfate improved control when in mixture. Ammonium sulfate improved control by clethodim in some instances irrespective of the broadleaf–sedge herbicide treatments.

Ganging of Resources via Fuzzy Manhattan Distance Similarity with Priority Tasks Scheduling in Cloud Computing

This paper proposes a fuzzy Manhattan distancebased similarity for gang formation of resources (FMDSGR) method with priority task scheduling in cloud computing. The proposed work decides which processor is to execute the current task in order to achieve efficient resource utilization and effective task scheduling. FMDSGR groups the resources into gangs which rely upon the similarity of resource characteristics in order to use the resources effectively. Then, the tasks are scheduled based on the priority in the gang of processors using gang-based priority scheduling (GPS). This reduces mainly the cost of deciding which processor is to execute the current task. Performance has been evaluated in terms of makespan, scheduling length ratio, speedup, efficiency and load balancing. CloudSim simulator is the toolkit used for simulation and for demonstrating experimental results in cloud computing environments. Keywords—clustering, pre-processing, quality of service, resource allocation.
Adventures in de Sitter space

This is my contribution to the Festschrift honoring Stephen Hawking on his 60th birthday. Twenty-five years ago, Gibbons and Hawking laid out the semi-classical properties of de Sitter space. After a summary of their main results, I discuss some further quantum aspects that have since been understood. The largest de Sitter black hole displays an intriguing pattern of instabilities, which can render the boundary structure arbitrarily complicated. I review entropy bounds specific to de Sitter space and outline a few of the strategies and problems in the search for a full quantum theory of the spacetime.
Reflective Core Values the Life of the Sundanese

Today, there are many Sundanese who do not have the typical personality and behavior of Sundanese people. Through this research, it is expected to get a picture of the phenomenon of instilling the values of Sundanese by habituation. The method used in this research is phenomenology method, with data collection techniques through observation, interview and documentation analysis. The results of this study are: Sundanese cultural moral values that are implemented in campus life create an atmosphere of harmony among leaders, lecturers, employees and students, so that the same harmonious atmosphere is experienced among students in campus life even though they come from different ethnicities, religions and cultures, and even it is experienced amongst foreign students who study here, both undergraduate and postgraduate level. The existence of Sundanese Core Value that crystallizes in the motto of luhung elmuna (high in knowledge), pengkuh agamana (strong religion), and jembar budayana (rich in cultures) for each graduate. The activities of Tri Dharma Perguruan Tinggi (three college assignments) is not enough to reach the values, but its typical mission of maintaining Sundanese culture and glorifying Islam appears in the campus atmosphere, tolerance of mutual respect and Silih Asih (love), Silih Asah (mutual coaching), Silih Asuh (mutual care) among the student. Keywords— core values; sundanese society; sundanese
Separable states improve protocols with finite randomness

It is known from Bellʼs theorem that quantum predictions for some entangled states cannot be mimicked using local hidden variable (LHV) models. From a computer science perspective, LHV models may be interpreted as classical computers operating on a potentially infinite number of correlated bits originating from a common source. As such, Bell inequality violations achieved through entangled states are able to characterize the quantum advantage of certain tasks, so long as the task itself imposes no restriction on the availability of correlated bits. However, if the number of shared bits is limited, additional constraints are placed on the possible LHV models, and separable, i.e. disentangled states may become a useful resource. Bell violations are therefore no longer necessary to achieve a quantum advantage. Here we show that, in particular, separable states improve the so-called random access codes, which is a class of communication problem wherein one party tries to read a portion of the data held by another distant party in the presence of finite shared randomness and limited classical communication. We also show how the bias of classical bits can be used to avoid wrong answers in order to achieve the optimal classical protocol and how the advantage of quantum protocols is linked to quantum discord.
A QUANTITATIVE ANALYSIS OF SQUASH SHOT ACCURACY

The purpose of this study was to examine the validity of the Hunt Squash Accuracy Test (HSAT) for predicting within-game performance on specific shot types. A correlation analysis compared the accuracy of specific shots during tournament match-play to the accuracy of the corresponding shot type in the HSAT. The correlation of the overall HSAT score against tournament rank was significantly large (0.95), as were the total % shot accuracy (0.90), total % backhand (BH) accuracy (0.94) and total % forehand (FH) accuracy (0.77) correlations. The only specific HSAT shot types with significantly large correlations to the corresponding match-play shots were; BH straight drive (0.92) and BH straight volley (0.97). The remaining shot types; boast, volley-drop and drops all showed non-significant correlations on both the BH and FH sides.
Mexico: what is the impact of monetary policy on unemployment rates?

In this paper we analyse the effects of a monetary policy shock on Mexican unemployment rates. Unlike previous studies, this one re-estimates unemployment to produce alternative rates comparable to those of the Organization for Economic Cooperation and Development (OECD) member countries. We find that in response to tightening monetary policy, unemployment increases with a characteristic hump-shaped pattern also found in other studies. Our results are robust to different assumptions about the nature of Mexico's labour market.
Analysis of Rainfall and Temperature Trends in Gomti River Basin

Analysis of trends in hydro-climatic variables such as rainfall, temperature and stream flow provide useful information for planning of water resources, control of flood, management of drought and agricultural production. Trends in rainfall (1982-2011) and temperature (1972-2007) in districts of Gomti River basin were assessed using the Mann-Kendall and Sen’s slope estimator. Streamflow (19822012) at the downstream end of the basin, Maighat was also assessed and relationships between trends in streamflow and rainfall were evaluated. All the districts in the upstream area showed significant increasing trend in annual rainfall (p < 0.05) while downstream areas showed decreasing trend. A similar drift was observed in the monsoon rain. Pre-monsoon rains had increasing trend, particularly in the month of May. In contrast, post-monsoon and winter rainfall were significantly decreasing especially towards the downstream areas. Streamflow was also reducing irrespective of the scale of assessment and this could be attributed partly to the decreasing rainfall. Decrease in rainfall and consequent decline in streamflow of the basin along with increasing temperature indicate possibility of dryness in the lower basin over the years. The results of this study could be helpful in implementing adaptation and mitigation strategies for alleviating the environmental and livelihood threats in Gomti River basin.
Objective review of de novo stand‐alone error correction methods for NGS data

The sequencing market has increased steadily over the last few years, with different approaches to read DNA information prone to different types of errors. Multiple studies demonstrated the impact of sequencing errors on different applications of next‐generation sequencing (NGS), making error correction a fundamental initial step. Different methods in the literature use different approaches and fit different types of problems. We analyzed 50 methods divided into five main approaches (k‐spectrum, suffix arrays, multiple‐sequence alignment, read clustering, and probabilistic models). They are not published as a part of a suite (stand‐alone), and target raw, unprocessed data without an existing reference genome (de novo). These correctors handle one or more sequencing technologies using the same or different approaches. They face general challenges (sometimes with specific traits for specific technologies) such as repetitive regions, uncalled bases, and ploidy. Even assessing their performance is a challenge in itself because of the approach taken by various authors, the unknown factor (de novo), and the behavior of the third‐party tools employed in the benchmarks. This study aims to help the researcher in the field to advance the field of error correction, the educator to have a brief but comprehensive companion, and the bioinformatician to choose the right tool for the right job.

The Welfare Impacts of Local Investment Projects: Evidence from the Guatemala FIS

This paper assesses the welfare impacts of local investments projects in rural areas of Guatemala. Using census track data from two rounds of the Guatemalan population census, as well as administrative data on investment projects, the authors estimate the impact of education, sanitation, productive, and total investment activities at the village level on measures of welfare. This is the first impact evaluation of social funds in Guatemala, and also the first paper that uses village level data, and both a multi-treatment effect approach and the generalized propensity score with continuous treatments to analyze this type of interventions. The outcome is such that local investment in schools significantly boosts enrollment and investments in water and sewerage significantly improved measures of access to water. The authors also examine the welfare impacts in regards to infant mortality and school progression.
Managing sudden transportation disruptions under delivery delay and quantity loss

Transportation disruption, a common source of business interruptions, can cause significant economic loss to a lean supply chain. This paper studies a lean, two-stage suppliermanufacturer coordinated system where a sudden disruption interrupts the transportation network, creating delivery delays, and product quantity losses. We develop a model to generate a recovery plan after a sudden disruption occurrence, to minimize the negative impacts of the disruption. At the same time, given the computational intensity and problem complexity, three heuristics based on the delivery delay and fractional quantity loss caused by a sudden disruption are developed. We conduct a number of numerical experiments to validate our proposed solution methods, and a scenario-based analysis to test the model and analyse the impact of sudden transportation disruption under three disruption scenarios. The performance of presented heuristics against the Generalized Reduced Gradient method are compared. The results reveal that the proposed heuristics can generate a recovery plan accurately and consistently.
Reduced gene flow in a vulnerable species reflects two centuries of habitat loss and fragmentation

Understanding the effects of landscape modi ﬁ cation on gene ﬂ ow of fauna is central to inform-ing conservation strategies that promote functional landscape connectivity and population persistence. We explored the effects of large-scale habitat loss and fragmentation on spatial and temporal patterns of gene ﬂ ow in a threatened Australian woodland bird: the Grey-crowned Babbler Pomatostomus temporalis . Using microsatellite data, we (1) investigated historical (i.e., pre-fragmentation) and contemporary (i.e., post-fragmentation) levels of gene ﬂ ow among subpopulations and/or regions, (2) identi ﬁ ed ﬁ rst-generation migrants and likely dispersal events, (3) tested for signatures of genetic bottlenecks, (4) estimated contemporary and historical effective population sizes, and (5) explored the relative in ﬂ uences of drift and migration in shaping contemporary population structure. Results indicated that the functional connectivity of landscapes used by the Grey-crowned Babbler is severely compromised in the study area. The proportion of individuals that were recent immigrants among all subpopulations were low. Habitat fragmentation has led to a clear division between subpopulations in the east and west, and the patterns of gene ﬂ ow exchange between these two regions have changed over time. The effective population size estimates for these two regions are now well below that required for long-term population viability ( N e < 100). Demographic history models indicate that genetic drift was a greater in ﬂ uence on subpopulations than gene ﬂ ow, and most subpopulations show signatures of bottlenecks. Translocations to promote gene ﬂ ow and boost genetic diversity in the short term and targeted habitat restoration to improve landscape functional connectivity in the long term represent promising conservation management strategies that will likely have bene ﬁ ts for many other woodland bird species.
RESPONSE OF BALANITES AEGYPTIACA ( L . ) DEL . VAR . AEGYPTIACA SEEDLINGS FROM THREE DIFFERENT SOURCES TO WATER AND SALINITY STRESSESS ELFEEL

Water and salinity are main co-occurring stresses affecting plant growth and development in arid lands. In this study interactive effects of water and salinity stresses on Balanites aegyptiaca seedlings from three different sources (SD5.1, SD6.2 and KSA) were assessed in potted experiment under greenhouse conditions. The effect was measured on stomatal conductance (Gs), specific leaf area (SLA), seedling quality (Shoot to Root ratio (S/R), Dickson Quality Index (DQI) and Sturdiness Quotient (SQ)), Nutrient uptake (N content, K/Na and Ca/Na ratios) and growth. The seedlings were either watered twice a week (well watered) or every two weeks (water stressed), in addition to four salt concentrations (fresh water as control, 5 dS m, 7 dS m and 9 dS m EC). Water and salinity stresses resulted in reduced Gs, SLA, DQ, SQ and S/R, associated with lower height and root collar diameter. However, irrespective of salt concentration, water stressed seedlings displayed substantial reduction in Gs, indicating that Gs is among the most important water conservation strategy for this species. S/R also, remarkably decreased in water stressed seedlings, but, within watering treatment it was increased with increasing salt concentration. SLA and DQI were more affected by salinity stress, due to the increased leaf weight with increasing salinity. N content was more sensitive to water stress than salinity. Both Ca/Na and K/Na ratios were decreased with increasing salt concentration. The three sources exhibited significant variation in their response to water and salinity stresses. SD5.1 displayed higher values in most of studied traits. Gs and S/R may be considered as fitness responses of this species to water stress, while DQI, SLA and K/Na can serve as good indicators to measure response to salt stress.
I DENTIFICATION OF AREAS OF ENDEMISM FROM SPECIES DISTRIBUTION MODELS : THRESHOLD SELECTION AND N EARCTIC MAMMALS

We evaluated the relevance of threshold selection in species distribution models on the delimitation of areas of endemism, using as case study the North American mammals. We modeled 40 species of endemic mammals of the Nearctic region with Maxent, and transformed these models to binary maps using four different thresholds: minimum training presence, tenth percentile training presence, equal training sensitivity and specificity, and 0.5 logistic probability. We analyzed the binary maps with the optimality method in order to identify areas of endemism and compare our results regarding previous analyses. The majority of the species tend to have very low values for the minimum training presence, whereas most of the species have a value of the tenth percentile training presence around 0.5, and the equal training sensitivity and specificity was around 0.3. Only with the tenth percentile threshold we recovered three out of the four patterns of endemism identified in North America, and detected more endemic species.The best identification of areas of endemism was obtained using the tenth percentile training presence threshold, which seems to recover better the distributional area of the mammals analyzed.
Investigation of Liquid Water Content of a Compressed PEMFC GDL Using Micro-Computed Tomography

With the current lack of understanding of the water transport phenomenon in the porous gas diffusion layers (GDLs) of the polymer electrolyte membrane fuel cells (PEMFCs), GDL designs are primarily implemented on a costly trial-and-error basis. In this work, an ex-situ device, suitable for micro-computed tomography (micro-CT) imaging, was designed to facilitate liquid water invasion of a GDL sample under flow field compression. The millimeter-scale apparatus allows for water injection from a point source with an opening diameter of 0.8 mm. A sample of felt-based Freudenberg GDL (H2315) was examined for the current study. Using micro-CT, the sample was scanned, before and after water invasion, to obtain high resolution, three-dimensional reconstructions of the dry GDL microstructures, as well as the liquid water patterns after breakthrough. These results were used to find the effect of liquid water content on the effective through-plane porosity for the felt-based Freudenberg GDL.Copyright © 2012 by ASME
TCC : A Novel Cloud Service for Cloud-deployed Applications

Applications with a dynamic workload demand need access to a flexible infrastructure to meet performance guarantees and minimize resource costs. While cloud computing provides the elasticity to scale the infrastructure on demand, cloud service providers lack control and visibility of user space applications, making it difficult to accurately scale the infrastructure. Thus, the burden of scaling falls on the user. That is, the user must determine when to trigger scaling and how much to scale. Scaling becomes even more challenging when applications exhibit dynamic changes in their behavior. In this paper, we propose a new cloud service, Trusty Compute Cloud (TCC), which spontaneously scales the infrastructure to meet the user-specified performance requirements, even when multiple user requests execute concurrently.
Changes in Land Distribution of Polar Bears in Western Hudson Bay

We examined the capture locations of polar bears ( Ursus maritimus ) on land in western Hudson Bay over 19 years (1986–2004) to assess temporal trends in the distribution of the population. We found that the distribution of bears of most age and sex groups shifted northward and eastward over the study. The causes of these shifts may be related to an altered population structure, changing environmental conditions, or a combination of both factors. Segregation by age, sex, and reproductive status persisted over time as found in earlier studies, but more females with young were within 5 km of the coast after 2001 than before. The distribution changes were correlated with the timing of sea-ice breakup, which now occurs, on average, about three weeks earlier than it did 30 years ago. While environmental conditions may have influenced polar bear distribution, the reduction in the number of large adult males along the coast may also have affected distribution patterns, allowing adult females to remain closer to the coast in more recent times.
Enhancing an Object Database with Profiling Information to Improve Agile Information Systems Development

This thesis extends the agile development cycle with modules for optimizing persistent object-oriented data models. The extension consists of two analyzers, a static model analyzer and an analyzer built on top of a database profiler. Both modules guide application developers in the process of refactoring a data model by means of recommendations. A prototype implementation has been developed and integrated into AgileIS, an existing environment tailored to the needs of agile developers which is developed within the Global Information Systems Group.
