Self-Driving Autonomous Car using Raspberry Pi

— In the past decade or two, self-driving cars have been drawing a considerable attention for various applications in military, transportation and industrial production. Here we present a remote controlled car which can drive itself to the selected destination using the voice commands as input. This car will be able to provide real time obstacle detection and path planning in a dynamic environment with the help of a Raspberry-Pi controller. The car uses Ultrasonic sensors for obstacle detection, a Pi-camera for obstacle identification and a microphone for voice control. The car will contain a cognitive map based model for localization and mapping, which will contain source and destination data. The proposed system is very inexpensive and efficient as compared to the other available systems.
Schistosoma mansoni infection in a natural population of olive baboons (Papio cynocephalus anubis) in Gombe Stream National Park, Tanzania

Infection with Schistosoma mansoni was studied in 5 troops of olive baboons (Papio cynocephalus anubis) in Gombe Stream National Park, Tanzania. Three troops were infected with S. mansoni. An aggregated distribution of parasites was observed among hosts. Troop membership was found to be the most significant factor influencing parasite prevalence. Age and reproductive status had no significant effect, but there was a trend for males to acquire higher levels of infection. However, age–prevalence curves showed a high infection in young baboons declining in the older baboons. Behavioural components of exposure – as measured in water-contact pattern – may be related to parasite burden. A ‘peak shift’ between infection in different age-classes in the different troops was observed: troops with higher schistosome prevalences displayed an earlier peak in prevalence of infection. The baboon troop with the most contact with people showed highest prevalence of infection possibly due to longer exposure to the parasite than the other troops and/or higher host density.
Hardware Factors Influencing Interlayer Bonding Strength of Parts Obtained by Fused Filament Fabrication

Current paper investigates the influence of hardware setup and parameters of a 3D printing process based on fused filament fabrication (FFF) technology on resulting sample strength. Three-point bending of samples printed with long side oriented along Z axis was used as a measure of the interlayer bonding strength. The same CAD model was converted into NC-programs through same slicing software to be run on four different desktop FFF 3D printers, out of filament of same brand and color. Within all the printers same ranges of layer thickness values from 0.1 to 0.3 mm and feed rates from 25 to 75 mm/s were planned to be varied. All the machines demonstrated statistically almost identical values of maximum flexural strength, however the different machines exhibited maximum sample strength with different combinations of varied parameters. Among all the hardware factors observed, the most important was proved to be extruder type, direct or Bowden. This feature fundamentally changes the nature of studied parameters influence onto the resulting strength of the FFF process. For the extruders of Bowden type the length of flexible guiding tube is of great importance.All the machines demonstrated statistically almost identical values of maximum flexural strength, however the different machines exhibited maximum sample strength with different combinations of varied parameters.

Effect of various dietary enzymes on energy digestibility of diets high in distillers dried grains with solubles for broilers.

SUMMARY Two trials of similar experimental design were conducted to assess the effects of various dietary enzymes on energy digestibility of diets high in distillers dried grains with solubles (DDGS) for broilers. A 2 × 4 factorial arrangement of treatments was used in which a cornsoybean meal control diet and a diet with 30% DDGS were supplemented with 2 different commercial enzyme products. In addition to the unsupplemented control, each enzyme was fed at the level suggested by the manufacturer, twice the recommended level, and 4 times the recommended level. Allzyme SSF (Alltech, Nicholasville, KY) was used in the first experiment, and Rovabio Excel (Adisseo, Alpharetta, GA) was used in the second experiment. Male commercial strain chicks that were 15 (trial 1) or 20 (trial 2) d old were randomly assigned to the experimental diets, with each treatment replicated 3 times. Celite (Celite Corp., Santa Barbara, CA) was used as an indigestible marker. After a 5-d period of acclimation to the diets, excreta samples were collected. The energy contents of the diet and excreta were determined and digestibility of dietary energy was calculated. In both trials, there was a significant (P < 0.05) difference in gross energy digestibility between the corn-soybean meal control diets and diets with 30% DDGS. However, no significant improvement in gross energy digestibility was obtained by adding any level of the 2 enzymes. Moreover, no significant interactions were found between the basal diets and various enzyme levels. Therefore, addition of the enzymes used in these studies had no apparent beneficial effect on energy digestibility of corn-soybean meal diets or diets with a high level of DDGS.
Control Technique for Parallel Manipulator using PID

Parallel manipulators are quite efficient when compared with serial manipulators since it can be used in high speed applications. But control of parallel manipulator is quite difficult. In this paper, a adaptive PID control of parallel manipulator is done and its performance is verified. The control of parallel manipulator using PID proved to be quite efficient when compared with other existing control technique. With PID control the parallel manipulator is able to trace along the desired trajectory without any deviation. Here the manipulator was independent of the operational change and also is able consider the system dynamics . Also this method has a advantage of having low error rate . Here delta parallel manipulator is used to control scheme efficiency. Delta parallel manipulator is realized based on sim mechanics model.
The prognosis and changes of regional brain gray matter volume in MDD with gastrointestinal symptoms

Objective: It is common that major depressive disorder (MDD) is accompanied by gastrointestinal (GI) symptoms. However, few studies have focused on the clinical characteristics and its possible mechanism, while brain gray matter (GM) structure is important in the pathogenesis of GI symptoms. In this study, we aimed to investigate the basic clinical characteristics and regional GM volume changes in MDD accompanied by GI symptoms. Method: Patients with MDD (n=49) and age, gender, and educational level-matched healthy controls (n=30) were recruited. Patients with MDD were divided into two groups based on the GI status: MDD with (n=27) and without (n=22) GI symptoms. The 24-item Hamilton Depression Rating Scale (HAMD) was administered. T1-weighted anatomical images were obtained and analyzed. Correlation analysis was used to identify the possible associations between changed regional GM volume and GI symptoms and depressive symptoms. Results: The HAMD reductive ratio for 2 weeks of treatment in the GI symptoms group was significantly higher than the non-GI symptoms group (P<0.05). The regional GM volume showed significant differences among the three groups (Gaussian Random Field [GRF] correction, voxel-P<0.01, cluster-P <0.05). Compared with non-GI symptoms group, GI symptoms group exhibited significantly increased GM volume in the left hippocampus, left parahippocampal gyrus, right parahippocampal gyrus; and decreased GM volume in the right middle frontal gyrus, right precentral gyrus, right cuneus, right precuneus, right superior occipital gyrus (GRF correction, voxel-P <0.01, cluster-P <0.05). These altered brain areas were correlated with the GI symptoms, not depressive symptoms. Conclusion: The changed regional brain GM volume in GI-MDD group may be the pathogenesis for the GI symptoms. In addition, the GI symptoms may predict the prognosis of MDD.
Reliability of Radiographic Scoring Methods in Axial Psoriatic Arthritis

Important differences exist between axial psoriatic arthritis (AxPsA) and ankylosing spondylitis (AS). The Bath Ankylosing Spondylitis Radiology Index (BASRI), the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS), and the Radiographic Ankylosing Spondylitis Spinal Score (RASSS) were developed to score AS, and the Psoriatic Arthritis Spondylitis Radiology Index (PASRI) to score AxPsA. We aimed to develop a computerized scoring application and compare the intra‐ and interrater reliability of these scoring systems in AS and AxPsA.
Estimation of the Hydromotive Source Pressure from Ejecting Beats of the Left Ventricle

The relationship between peak isovolumic developed pressure (Pmax) and end-diastolic volume can indicate ventricular contractility. Therefore, we propose a practical method to estimate Pmax from the pressure curve of an ejecting contraction of left ventricle. For the estimation, we first considered the left ventricle a linear time varying hydromotive pressure source (HMP(t)) coupled in series with an internal impedance. To formulate the HMP(t) we Fourier analyzed isovolumic pressure curves obtained under various conditions in six dogs. Since the higher order harmonics were found to be very small, HMP(t) could be described simply as where Pd = end-diastolic pressure and w = 2/T in which T is duration of contraction. Finally, HMP(t) for ejecting contraction was estimated by fitting the equation to the isovolumic portions of the pressure curve of ejecting contractions. The estimated Pmax values correlated well with actually observed Pmax values (r = 0.951, N = 24). We conclude that the proposed technique can be used to estimate Pmax from a single ejecting beat.
Range perception through apparent image speed in freely flying honeybees

Abstract When negotiating a narrow gap, honeybees tend to fly through the middle of the gap, balancing the distances to the boundary on either side. To investigate the basis of this “centering response,” bees were trained to fly through a tunnel on their way to a feeding site and back, while their flight trajectories were filmed from above. The wall on either side carried a visual pattern. When the patterns were stationary vertical gratings, bees tended to fly through the middle of the tunnel, i.e. along its longitudinal axis. However, when one of the gratings was in motion, bees flying in the same direction as the moving grating tended to fly closer to while bees flying in the opposite direction tended to fly closer to the stationary grating. This demonstrates, directly and unequivocally, that flying bees estimate the distances of surfaces in terms of the apparent motion of their images. A series of further experiments revealed that the distance to the gratings is gauged in terms of their apparent angular speeds, and that the visual system of the bee is capable of measuring angular speed largely independently of the spatial period, intensity profile, or contrast of the grating. Thus, the motion-sensitive mechanisms mediating range perception appear to be qualitatively different from those that mediate the well-known optomotor response in insects, or those involved in motion detection and ocular tracking in man.
Structure and evolution of two related transcription units of Epstein-Barr virus carrying small tandem repeats

Two regions of the Epstein-Barr virus (EBV) genome carrying partially homologous clusters of short tandem repeats (NotI and PstI repeats) flanked by 1044 and 1045 base pairs with almost complete homology (DL and DR, left and right duplication, respectively) were most abundantly transcribed into poly(A)+ mRNA after induction with the tumor promoter 12-O-tetradecanoyl-phorbol-13-acetate. The nucleotide sequence of both repeat clusters and the conserved upstream regulatory sequences from the M-ABA EBV strain are presented. Nearly the whole part of the sequences coding for the RNAs is covered by the NotI and PstI repeats, respectively. The regulatory sequences for these genes are located in the homologous regions of 1044 and 1045 base pairs (DL and DR, respectively). A CAAT box, a TATA box, and other herpes simplex virus-like elements were identified for both transcription units. The initiation points and the 3' ends of both inducible RNAs were mapped by S1 nuclease analysis. Both genes have open reading frames and may potentially code for proteins with repetitive amino acid compositions. The structure of these two inducible EBV genes is discussed, and an evolutionary model is proposed for the generation of gene duplication in the M-ABA strain of EBV.
Evaluation of apical seal between single cone and cold lateral condensation techniques after post space preparation at different timing

Obturation technique may have an effect on the apical seal following post space preparation. This study aimed to evaluate the apical seal of single cone and cold lateral condensation obturation techniques after post space preparation at two different timing. A total of 120 decoronated, single-rooted human premolars were divided into two groups (n=50) based on canal preparation and obturation techniques; group A - hand ProTaper/ single cone and group B - modified double-flared/ cold lateral condensation. Each group was then subdivided into two subgroups (n=25) (subgroup I- post space preparation immediately after obturation; subgroup II- post space preparation 7 days later). The remaining 20 teeth served as positive and negative controls. The external root surface was coated with nail varnish, submerged in 2% methylene-blue dye and incubated at 37°C for 72 h. Each tooth was later sectioned apico-coronally at 1 mm interval and evaluated using dissecting microscope. The results revealed that obturation techniques do not affect the apical seal (p>0.05). Immediate post preparation groups achieved significantly better seal for both obturation techniques when compared with the delayed groups at the level 3 mm and above from the apex (p<0.05). Immediate post space preparation provides better apical seal regardless of obturation techniques used.
Longitudinal impact of interprofessional education on attitudes, skills and career trajectories: a protocol for a quasiexperimental study in New Zealand

Introduction Interprofessional practice is recognised as an important element of safe and effective healthcare. However, few studies exist that evaluate how preregistration education contributes to interprofessional competencies, and how these competencies develop throughout the early years of a health professional’s career. This quasiexperimental study will gather longitudinal data during students’ last year of preregistration training and their first 3 years of professional practice to evaluate the ongoing development of interprofessional competencies and the influence that preregistration education including an explicit interprofessional education (IPE) programme may have on these. Methods and analysis Participants are students and graduates from the disciplines of dentistry, dietetics, medicine, nursing, occupational therapy, oral health, pharmacy and physiotherapy recruited before their final year of study. A subset of these students attended a 5-week IPE immersion programme during their final year of training. All data will be collected via five written or electronic surveys completed at 12-month intervals. Each survey will contain the Attitudes Towards Health Care Teams Scale and the Team Skills Scale, as well as quantitative and free-text items to explore vocational satisfaction, career trajectories and influences on these. Students who attend the IPE programme will complete additional free-text items to explore the effects of this programme on their careers. Quantitative analysis will compare scores at each time point, adjusted for baseline scores, for graduates who did and did not participate in the IPE programme. Associations between satisfaction data and discipline, professional setting, location and IPE participation will also be examined. Template analysis will explore free-text themes related to influences on career choices including participation in preregistration IPE. Ethics and dissemination This study has received approval from the University of Otago Ethics Committee (D13/019). Results will be disseminated through peer-reviewed publications, conferences and stakeholder reports. Findings will inform future IPE developments and health workforce planning.
Application of Sparse Sampling to Accelerate the Hough Transform

A rotating lamp fixture includes a plurality of lamps, attached to an arm which extends outwardly from a housing preferably mounted to the ceiling of a building. The arm is connected through a torque coupling and a gear train to the shaft of an electrical motor. The motor imparts a relatively slow circular or orbital motion to the lamps through the arm for serving as an artificial light source. The provision of a rotating light source reduces by at least one-third the number of fixed light sources needed for effectively controlling the growth of vegetation. The rotating lamp fixture increases the growth rate, improves the uniformity of growth, and/or precisely controls one or more other growth characteristics of the vegetation. Other features are also disclosed.
Internal and External Evidence in the Identification and Semantic Categorization of Proper Names

We describe the proper name recognition and classification facility ("PNV') of the SPARSER natural language understanding system. PNF has been used very successfully in the analysis of unrestricted texts in several sublanguages taken from online news sources. It makes its categorizations on the basis of 'external' evidence from the context of the phrases adjacent to the name as well as 'internal' evidence within the sequence of words and characters. A semantic model of each name and its components is maintained and used for subsequent reference. We describe PNF's operations of delimiting, classifying, and semantically recording the structure of a name; we situate PNF with respect to the related parsing mechanisms within Sparser; and finally we work through an extended example that is typical of the sorts of text we have applied PNF to.
Task Space Dynamic Analysis of Multiarm System Configurations

The aim of this article is to provide a systematic method to perform dynamic analysis in the task space for a sys tem composed of multiple arms holding a rigid object. The dynamic manipulability ellipsoid is introduced to obtain quantitative indices of the system's capability, in each configuration, of performing object accelerations along given task space directions. The ellipsoid is derived on the basis of the mapping of object accelerations onto joint driving torques via the proper kineto-static and dynamic equations of the system. The maximum joint torque limits are taken into account, and the effects of gravitational loads onto the ellipsoid are evidenced. Anal ysis of multiarm system configurations is carried out in a number of case studies.
Nonlinearity Effects Reduction of an AFM Piezoelectric Tube Scanner Using MIMO MPC

The design of a controller which compensates for the effects of creep, hysteresis, vibration, and cross-coupling in a piezoelectric tube scanner (PTS) is presented in this paper. The PTS is a key nanopositioning component installed in a commercial atomic force microscope (AFM) to perform scanning. The impediments to fast scanning due to PTS dynamics are: 1) the presence of mechanical resonances; 2) nonlinearities due to the piezoelectric characteristics; and 3) the cross-coupling effect between x- and y-axes in the PTS. In this paper, a multi-input multi-output model predictive control (MPC) scheme is designed to counteract the effects of creep, hysteresis, vibration, and cross-coupling in a PTS. Also, a damping compensator is included to suppress the vibration effect at its resonance frequency. The proposed controller achieves a high closed-loop bandwidth and significant damping of the resonant mode. To evaluate the performance improvement using the proposed control scheme, an experimental comparison with the existing AFM proportional-integral (PI) controller and a single-input single-output (SISO) MPC is conducted. Enhancement in the scanning speed up to 125 Hz is observed with the proposed controller.
Opportunities for resilient rail system development using natural language processing.

In this paper we examine a natural language processing and machine learning approach to help assess the quality of railway hazard logs. The focus is on highlighting red flags in the hazard log content to help improve the accuracy and quality of the contents and so the speed of risk reviews. Data is presented that indicate the approach has potential for significant savings in time and increased quality. The tool is one of a number that we are developing as part of an initiative to improve rail system development and operation by employing artificial intelligence (AI) to augment existing methods in the context of a wider system engineering approach. This will in turn lead to rail systems becoming more sustainable and resilient.
