Facial Emotion Detection through Deep Covolutional Neural Networks

Our society has evolved to a threshold where use of machines to automate mundane tasks is constantly increasing in daily life. Providing machines with capability to develop perception from their environment can lead them to perform a great variety of tasks. Facial emotion detection is crucial sub-part of machine perception development. In this article we present a deep learning based approach for Facial emotion Detection. Our model uses a Convolutional Neural Network (CNN) to learn deep features for classification of facial images into one of 22 emotion (Basic 7 + Compound 15) categories considered in this study. We trained our CNN model with the images dataset from Martinez et al. Our Facial Emotion Detection model was developed using keras with theano backend and implemented on a GPU-powered testbed. Our model achieved 67.6% accuracy for basic emotions and 33% accuracy for compound emotions.
Sexual dimorphism in head size and food habits in the blue-tailed skink Eumeces elegans

We collected blue-tailed skinks Eumeces elegans during May-July 2002 and 2003 from a mountain population in Taishun, Zhejiang, with an aim to uncover the determinants of sexual dimorphism in head size. The captured skinks were preserved in 5% formalin, and were later measured and dissected to provide original data on morphology, sexual dimorphism, dietary habits and reproductive biology. The preserved specimens were measured for snout-vent length (SVL), tail length, head length (from the snout to the anterior edge of tympanum) and head width (taken at the posterior end of the mandible). After measurements, the specimens used to analyze dietary habits were opened with a mid-ventral incision, and prey items in the stomach were removed for identification and measurement. The stomach contents of each specimen were classified as animals (which were usually placed into specific taxonomic categories) or plants (primarily seeds). Relatively undigested prey items were measured for length. Sex and reproductive status were determined by visual inspection of gonads, and individuals larger than 69 mm SVL were classified as mature. Males are the larger sex, because adult males attained larger mean and maximum sizes (SVL) than females. Skinks larger than 50 mm SVL had already showed sexual dimorphism in head size (both head length and head width), with males having larger heads than females of the same body size. The differences in head size between the sexes were much more pronounced in adults than in sexually dimorphic juveniles with SVL ranging from 50 to 69 mm, largely because the ontogentic shifts in the rate at which head size increases with increasing SVL occurred in both females and males. Because adult males with larger heads have the advantage of winning the male-male contests for resources (including mates), larger heads evolved in males primarily due to the directional action of sexual selection. Unlike males, females with greater abdominal cavities may take advantage of holding more and/or larger eggs (offspring). Given that resources available to any females are limited, increasing carcass (abdomen) growth, thereby increasing reproductive output, must reduce head growth. Thus, smaller heads in adult females primarily result from the action of fecundity selection. Dietary habits shifted with body size, but did not differ significantly between the sexes of the same body size. Larger skinks were able to take larger prey and, thus, had wider food niche breadths, as compared to smaller ones. Data on ontogentic shifts in dietary habits do not provide evidence showing an important contribution of the divergence in head size to the segregation of food niche between the sexes. Thus, we conclude that sexual dimorphism in head size in Eumeces elegans is primarily determined by the ultimate factors (sexual selection for males and fecundity selection for females) rather than the proximate environmental factors and the avoidance of inter-sexual competition for food.
LFC for Autonomous Hybrid Micro Grid System of 3 Unequal Renewable Areas using Mine Blast Algorithm

This paper ensures the feasibility of the proposed 3-area hybrid micro grid system (3A-HµGS) comprising of highly intermittent energy sources like wind turbine generator (WTG), parabolic trough collector (PTC), and PV arrays. Renewable energy sources (RES) inherently set in power and frequency oscillations as these sources (RES) are extremely influenced by climatic behavior that’s why the erection of 3A-HµGS as a controlled dispatch able unit is in fact very difficult to be realized but this proposed system has considered diesel engine generator (DEG) as a back-up source and the energy storage system (ESS) like battery, ultra-capacitor and fuel cell as the dynamic devices to make it controllable and reliable. Unwanted frequency deviation has been restricted to a satisfactory limit through GA, PSO and MBA based proportional integral derivative (PID), proportional integral derivative with filter (PIDN) and 2 degree of freedom PID (2DOF-PID) controllers. MBA based 2DOF-PID controllers provide the best coordination among RES, ESS, and DEG to maintain the power quality of 3A-HµGS. A qualitative and quantitative analysis of the dynamic responses under all the controlling actions clearly exhibits the efficacy of the proposed system. Moreover, the system remains stable even after incorporation of natural disturbances like change in wind velocity and solar irradiances which ensure the feasibility and practicality of the proposed 3A-HµGS.
Evolving GPU-Accelerated Capsule Networks

Capsule Networks exploit a new, vector-based perceptron model, providing feature instantiation parameters on top of feature existence probabilities. With these vectors, simple scalar operations are elaborated to vector-matrix multiplication and multi-vector weighted reduction. Capsule Networks include convolutional layers which take the initial input and help it become a tensor. A novel data abstraction maps the individual values of this tensor to one-dimensional arrays but is conceptualized as a 2D grids of multi-dimensional elements. Moreover, loss function thresholds and architectural dimensions were arbitrarily set during the introduction of Capsule Networks. While current machine learning libraries provide abstractions for convolutional layers, a TensorFlow optimization requires structural overhead for a full Capsule Network implementation. They lack simple optimizations specifically for Capsule Network data allocation. This thesis presents a scalable GPU optimization for the training and evaluation of Capsule Networks. Furthermore, hyperparameters are adjusted with the help of a multi-objective evolutionary algorithm (MOEA) to minimize the loss function while maximizing accuracy.

Association of cholesteryl ester transfer protein TaqIB polymorphism with blood lipid profile

Objective To study the TaqⅠB RFLP in the first intron of the cholesteryl ester transfer protein(CETP) gene,blood lipid profile and CETP mass in order to determine their association.Methods CETP genotypes of 186 subjects were analyzed by means of polymerase chain reaction and restricted fragment length polymorphism(RFLP). The levels of blood lipid profile and CETP concentration in different gene types were compared.Results B1 homozygotes(B1B1:1.20±0.33 mmol/L) had lower HDL C levels than B1B2 or B2B2(B1B2:1.33±0.36 mmol/L,B2B2:1.37±0.24 mmol/L)did. B1 homozygotes had lower ApoA1 levels as compared with B2 homozygotes(1138.42±223.57 mg/L vs 1276.70±142.63 mg/L). The difference was especially significant in male subjects. TaqⅠB polymorphism explained 1.9% of the variability in HDL C and was an independent factor influencing HDL C level. There was no significant negative correlation between plasma CETP and HDL C concentration. The association of TaqⅠB polymorphism with plasma CETP levels was not identified in this study. Conclusion CETP TaqⅠB variant was a significant determinant of HDL C.

Allicin inhibits hippocampal neuronal apoptosis induced by global cerebral ischemia-reperfusion

AIM: To explore the effect of allicin on hippocampal neuronal apoptosis induced by global cerebral ischemia - reperfusion and its mechanisms. METHODS: Wistar rats were subjected to 15 min global cerebral ischemia followed by 72 h reperfusion. Flow cytometry (FCM) was used to evaluate the rate of hippocampal neuronal apoptosis and colorimetric method was used for the measurement of nitric oxide (NO) , malondialdehyde (MDA) contents and superoxide dismutase (SOD) activity in hippocampal tissue. RESULTS: Neuronal apoptotic rate, nitric oxide and malondialdehyde contents in hippocampal tissues of rats in I - R group were significantly higher than those in sham group. However, superoxide dismutase activity in hippocampal tissues of rats in I - R group was obviously lower than that in sham group. Allicin pretreatment inhibited the above changes in a dose-dependent manner. CONCLUSION: Allicin hihibits hippocampal neuronal apoptosis induced by global ischemia-reperfusion insult through anti - oxidation. The anti - oxidation action of allicin may be one of the mechanisms of inhibitory effects on hippocampal neuronal apoptosis.

Assessment of genetic relationship in Crataegus genus by the apple SSR primers

The transferability of SSRs information from one species to another species has been proven. In this study, we attempted to transfer 141 SSR primers derived from apple to hawthorn, and study the genetic relationship among 37 hawthorn germplasms, belonging to 8 species. Only 10 primer pairs which successfully amplified clear and polymorphic band patterns indicating single locus were selected for hawthorn genetic analysis. A total of 91 alleles were detected from 10 SSR loci, with an average of 9.1 alleles from 3 to 13. Heterozygosity for individual locus ranged from 0.432 to 0.790, with an average heterozygosity for 10 loci equaling 0.688. Twenty accessions could be differentiated from each other. seventeen accessions that could not be distinguished were divided into 3 groups: the first group included 3 genotypes of Crataegus brettschneideri; the second and the third group included 2 and 12 cultivars of C. pinnatifida var. major respectively. UPGMA cluster analysis of the 37 hawthorn accessions based on SSR markers resulted in 2 clusters which appeared to be related to traditional morphology classification. Cluster I contains 6 wild species of hawthorn, and the accessions of C. brettschneideri, C. pinnatifida and C. pinnatifida var. major grouped in cluster II.
Performance Analysis of Drive-thru Internet Access

Drive-thru Internet is considered to be an important solution to provide Internet access for vehicles. By deploying cost-effective and high bandwidth roadside WiFi networks, a vehicle can upload/download considerable data when drive through the coverage area, whereby a myriad of automotive applications can be employed, such as intelligent transportation system, infotainment applications like video/audio streaming, webpage browsing, etc. However, the high mobility of vehicles leads to the intermittent connection between a vehicle and roadside Access Points (APs), which would cause the Internet access delay and throughput degradation. In this thesis, we propose comprehensive modeling and analysis for the drive-thru Internet access performance considering the overhead of the access procedure, which includes the steps of network detection, user authentication and network parameters assignment. We also consider the situation that a vehicle drives through multiple roadside APs' coverage areas and evaluate the performance of traffic offloading from cellular networks to roadside WiFi networks. In specific, firstly, we develop an analytical model to study the dependency of the drive-thru Internet access delay with different factors, i.e., the wireless channel conditions, the number of co-associated WiFi clients, and the employed authentication mechanism, such as the WiFi Protected Access II (WPA2)-Pre-Shared Key (PSK) and the WPA2-802.1X modes. The access procedure is modeled as a discrete Markov chain to calculate the time to exchange all management frames and to evaluate the Internet access delay. The accuracy of the analytical model is studied via computer simulations, as well as experimental testing using Commercial Off-The-Shelf (COTS) WiFi products, together with a channel emulator that emulates the wireless channel conditions in a vehicular environment. Simulation and experiment results validate the accuracy of the proposed analytical model which provides useful guidelines for future selection/development of suitable WiFi network access schemes in a vehicular environment. Secondly, we take a further step to analyze the throughput performance of the drive-thru Internet access. The mobility of the vehicle is modeled as the transition of a series of zones in the coverage area, which is defined based on the relationship between the WiFi link rate and the distance of the AP and the vehicle. A three dimensional (3D) Markov model is proposed to combine the zone transition process and the transmission of the management frames and calculate the average throughput under conditions of different numbers of co-associated WiFi clients, channel qualities and different access protocols. Thirdly, we consider that when the vehicle drives through multiple roadside WiFi networks, and employ the Vehicle-to-Vehicle (V2V) assisted WiFi offloading mechanism, where nearby vehicles that associated to different APs can use their idle WiFi resource to offload part of peer's data traffic. The offloading performance is calculated by…
CHANGES OF CHLOROPLAST PIGMENTS OF MAIZE LEAVES AFTER SPACE FLIGHT IN RECOVERABLE SATELLITE

Dred seeds of maize inbred lines were carried by recoverable satellite flying at an altitute of 175~253 km from sea level . The charges of absorption spectra of acetone extracts and cbloroplast pigment contents of maize leaves were studied . It shoed that the light absorption characteristics of space-flight treatment (SP) were quite similar to those of the corresponding ground controls(CK) at the same time of sampling.However ,the absorbance of the SP were less than C K at absorption peaks of chlorophyll a and b,respectively . The contents of chlorophyll a and chlorophyll b of SP were significantly reduced,and the reduction of chlorophyll b far exceeded chlorophyll a. The contents of chlorophyll a+b were reduced so much that the total amount of their cbloroplast pigments was lowered, but Ca/ Cb ratio tended to be higher in compassion with CK.
New Reconfigurable L-Band Digital Aeronautical Communication System.

To meet an ever-increasing demand of the spectrum for communication between aircraft and ground terminals, orthogonal frequency division multiplexing (OFDM) based L-band (960-1164MHz) Digital Aeronautical Communication System (LDACS) has been recently proposed as an alternative to existing narrowband systems. However, OFDM based LDACS needs additional control signaling for time and frequency alignment and the use of cyclic prefix and high out-of-band emission limits the spectrum utilization efficiency to less than 50%. In this paper, a new waveform has been proposed which offers better spectrum utilization than OFDM without compromising on computational complexity and interference to legacy users in L-band. It also allows transceivers to dynamically adapt the transmission bandwidth to meet the desired quality of service. Since the proposed waveform employs a reconfigurable multiband linear phase filter, it is referred to as reconfigurable filtered OFDM (Ref-OFDM). Simulation results and extensive analysis show that the proposed Ref-OFDM offers around 40 dB better out-of-band emission than OFDM which in turn leads to significant increase in the transmission bandwidth for a given BER and interference constraints. The computational complexity of Ref-OFDM is slightly higher than that of OFDM but it is significantly less than other waveforms making Ref-OFDM an attractive waveform for next generation air-to-ground communications. An end to end hardware prototyping of LDACS-DME coexistence is also presented in this report.
