Since from the last decade, the importance of efficient and robust face recognition becomes interesting research problem due to its growing demand in user authentication process across different applications. Several face recognition method designed by considering the challenges of constrained and unconstrained face acquisition. The performance of face recognition systems becomes worst while working with unconstrained and plastic surgery datasets. The unconstrained dataset may contain the significant variations in illumination, expressions, and face image quality. This paper proposed the novel face recognition framework which is built on top of hybrid face descriptor and hybrid features extraction technique. The purpose of hybrid face descriptor is to achieve the bridge the gap between spatial information and histogram representations to address the challenges of unconstrained face conditions efficiently. The hybrid features extraction includes the histogram features (single and multi-level) and invariant features. Since the moment invariant features become effective shape descriptor to address the challenges of unconstrained face images, we proposed 11 different invariant moments from the hybrid face descriptor. To normalize and reduce the features, we applied lightweight features selection technique. The experimental result shows that proposed face recognition framework improves the overall accuracy different datasets.

Human Development Index (HDI) is an indicator to see the ruling government achievement, especially in the human development aspect. It was introduced by United Nations Development Programme (UNDP) in their 1990 report and integrated three basic dimensions of human development, i.e., the ability to lead a long and healthy life, to acquire knowledge, and to achieve a decent standard of living. Indonesia itself was ranked 113 out of 188 UNDP countries and ranked fifth among ASEAN countries for HDI value based on UNDP Human Development Re-port 2016: Human Development for Everyone. In this study, we are trying to forecast Indonesia’s HDI using Exponentially Weighted Moving Average (EWMA) method. EWMA is a popular and widely used method to smooth out random fluctuations. Based on the experiments conducted in 34 provinces in Indonesia, EWMA has been successfully applied to forecast the human development index in Indonesia. It has an average score of MSE and MAPE values at 1.002279153 for MSE and 1.374754513% for MAPE.

The choice of colour palette in image processing of medical thermal images plays a crucial role and it essentially affects the interpretation and visualization of the thermal image. Even though it has remained a subject of criticism due to the difference of visualization as compared to the grayscale colour palette, the rainbow palette has been widely applied in medical image processing of thermal images. In this work, the rainbow colour palette and the grayscale colour palette were applied on the medical thermal images representing skin conditions and a comparative study was performed to assess their applicability and performance in the methodology applied. It is observed that both the palettes are suitable at different stages as part of methodology to study medical thermal images. Using the global thresholding techniques for foreground detection, the grayscale palette was found useful for image segmentation into background and foreground while the rainbow palette is effective when colour-based clustering is performed to segregate the object of interest into varying temperature zones.

As far as a rider is concerned, safety is the first priority while driving a vehicle. There have been significant changes over the years in the design of four wheeler in terms of security. During the design of vehicles manufacturers are incorporating many modifications to the existing model so that the security is more. But when the safety of motorbikes is concerned this is not true, as there exits some blind spots which are not visible to the rider through the mirrors. Blind spots are the rare quarter areas towards the rear of the vehicle on both sides, vehicles in the contiguous paths of the road may fall into these vulnerable sides and driver may not be able to see them using only the mirrors. In this paper we have introduced a new approach using machine learning tools to detect the obstacles and to alert rider and there by reducing the risk of collision. This system could reduce significant amount of risk that the rider is going to face because of the obstacles which are not visible through the mirrors.

Vector -borne diseases (VBDs) are one of the major problems of human are affecting adversely to people each year in every part of the world. In this work multiple decision-making technique is used to provide a better diagnosis for VBDs. It evaluates alternative diseases having contradictory symptoms. It is very tough to exactly determine crsiteria weight as well as rating of alternatives (diseases) on each criterion. Here VIKOR approach is applied for medical diagnosis of VBDs such as malaria, chikungunya, and dengue, and also used the notion of intuitionistic fuzzy set (IFS) theory to explain this concept. Furthermore, criteria selected according to relevant disease and weights assigned to them by medical experts. In order to accomplish the objective, patients’ data has been acquired using a questionnaire from three medical experts of Delhi region. The study shows that final outcomes are same as diagnosed by doctors regarding actual diseases as that by employing VIKOR technique based on questionnaire information. Thus, MCDM methodology can help in correct and timely diagnosis of VBDs and provides doctors a scientific diagnostic tool.

Wireless local area networks (WLANs) are growing very rapidly in recent years. With the growing popularity of the wireless network, risk of security attacks associated with wireless network is also growing. Access Points (AP) are used in many public places like airport and hospitals to provide the users internet facility. Due to the open nature of the wireless networks, it is vulnerable to many different types of threats. Main wireless threats are eavesdropping, man in the middle attack and evil twin attack etc. In this paper one such threat MITM (Man in the Middle Attack) is discussed. In this case attacker creates a Rogue Access Point (RAP) using the same parameters as that of original AP of the network, with the help of software. We propose a methodology to detect the MITM attack. Our algorithm use combination of RSSI (Received Signal Strength Indicator) value and sequence number for detecting this attack.

Due to depletion of natural aggregates the need for the usage of recycled aggregate in concrete has gained significance. In this regard, the present study is an attempt to evaluate the performance of M20 grade of concrete made with 100% recycled aggregate processed using various techniques. Handpicked aggregate from concrete rubble is used to prepare recycled aggregate concrete. The use of chemical admixture is mandatory to compensate the extra water (3 to 6%) required by the RCA (Recycled Aggregates). RCA treated with calcite mineral precipitating bacterial suspension enhances its surface permeability. RCA exposed to different acid concentrations improved the surface of the aggregate with the removal of the loosely adhered mortar. In thermal – mechanical method the recycled aggregates from rubble are heated in microwave to 300°C to remove adhered mortar from the aggregate and placed in a rotating drum containing iron balls. In chemical–mechanical method the recycled aggregate is exposed to Na2So4 and is subjected to freeze-thaw cycles to create mechanical to separate adhered mortar from RCA. In acid soaking beneficiation method the mortar around RCA is removed by immersing them in 5% HCl and H2SO4 for 24 hours. All the above mentioned recycled aggregate processing techniques are however to be tested in full scale to study the efficiency of these treatment techniques. Compressive strength and water absorption capacities of various concrete samples made with recycled aggregate prepared using above discussed processing techniques are evaluated.

Mathematics is one of the subjects which is learned at all levels of education. Ithappens because mathematics is used and needed in every aspect human activity. One of theabilities students must possess is the ability to solve problems. Facts in Indonesia show thatstudents' mathematical problem-solving abilities at both secondary and tertiary educationlevels are still not high. From previous studies reported that only 35% of students had problemsolvingskills, 25% of students were able to design completion plans and 20% of students hadthe ability to solve problems. The remaining 20% are students who have the ability to lookback at the completion steps. Looking at the research reports above, the teachers are expectedto choose the right strategy to be used in carrying out the learning process in the classroom sothat the goals that have been written in the teaching plan can be achieved. A learning modelcalled "Everyone is a Teacher Here (ETH)" is an alternative learning to improve students'mathematical problem solving abilities. The ETH Learning Model provides opportunities forall students to act as "instructors" to their peers or in other words "peer tutors". Anotheralternative learning that can be used to improve students' mathematical problem solving skillsis the Quantum Teaching learning approach. The Quantum Teaching Approach can givestudents an active learning that stimulates the student's brain so that learning can runoptimally. This Quantum Teaching Approach has an activity framework in the form of Grow,Experience, Name, Demonstrate, Repeat, and Celebrate.

Recently, the importance of the infiltration process in agriculture and the environ- ment has resulted in an upsurge of interest by soil and water scientists to model the process for quantitative application. A study was conducted on the University of Cal- abar Teaching and Research Farm, Calabar to evaluate the effect of oil palm (OP) and arable farm (AF) land use systems on the Green-Ampt (GA), Philip (P), Kostiakov (K), Horton (H) and Mezencev (MZ) infiltration models, as well as the applicability or efficiency of the models to predict infiltration into the soils. Infiltration data were obtained with double-ring infiltrometer, and the parameters of the models were obtained through curve-fitting. Model accuracy was evaluated with the Willmott’s index of agreement (W), chi-square (X2), coefficient of determination (R2), root mean square error (RMSE) and mean error (ME) test statistics. The results showed that soil under oil palm had measured cumulative infiltration and infiltration rate of 72.81 cm and 14.10cm/hr while arable farm had 74.76 cm and 12.92 cm/hr, respectively. The cumulative infiltration predicted by Philip and Kostiakov models were very close to the field data for OP and AF. Horton and Mezencev models underestimated the infiltration process because their ME values were negative while Green–Ampt, Kostia- kov, and Philip overestimated the infiltration process as they had positive ME values. In terms of accuracy and applicability, the order of performance was P>K>MZ>GA>H. Therefore, the Philip and Kostiakov models could be used to pre- dict infiltration into the soils, but that the Philip model was superior to the Kostiakov model for the University of Calabar Teaching and Research Farm and similar soils in other ecologies.

Published: August 2019

An assessment of the effects of erosion on the soil productivity of Agbor area of Delta State, Southern Nigeria was evaluated. The investigation involved three (3) soils (Virgin forest, Arable cropping and Traffic soils) with history of erosion. The aggregate stability, mean weight diameter (MWD) and state aggregation of soil of the area was studied, since these soils properties have direct relationship with soil erodibility. The results reveals that the soil texture was loamy sand. mean weight diameter values ranged from 0.56 mm (Traffic), 0.74 mm (arable cropping) and 1.25 mm (virgin forest). State of aggregation ranged from 12.00 mm (arable cropping), 23.00 mm (traffic) and 43.3 mm (virgin forest). Mean porosity 65.4 mm (traffic soils), 72.1 mm (arable cropping) and 77.0 mm (virgin forest). Mean aggregate stability ranged from 74.4 mm (traffic soils), 25.8 mm (arable cropping) and 48.00 mm (virgin forest). Soil organic matter mean values ranged from 0.08 g/ kg (traffic soils), 1.90 g/ kg (arable cropping) and 2.72 g/ kg (virgin forest), respectively. The results recorded for virgin forest relative to arable cropping and traffic soils in most of the soil properties evaluated is an indi- cation that current land use practices in Agbor area contribute immensely to the accelerated soil degradation observed in the area.

Mempelajari pemrograman sebaiknya dimulai dari cara-cara yang sederhana dan menyenangkan, terutama untuk seorang siswa. Apabila diawal  dikenalkan dengan cara-cara yang sulit dipahami dan terkesan membosankan maka akan mengurangi minat belajar siswa. Kemudian jika dipaksakan untuk belajar di khawatirkan nantinya akan menghasilkan sistem yang tidak maksimal. Meskipun siswa mempunyai algoritma untuk menyelesaikan suatu permasalahan yang berbeda-beda  tapi akan lebih baik kita gunakan algoritma yang lebih ringkas dan sederhana. Target silmulasi ini adalah SMK yang ada di kota Pekanbaru. Untuk mengukur kertercapaian kegiatan penelitian menggunakan scale likert dimana Skala Likert adalah skala yang digunakan untuk mengukur persepsi, sikap atau pendapat seseorang atau kelompok mengenai sebuah peristiwa atau fenomena sosial, berdasarkan definisi operasional yang telah ditetapkan oleh peneliti. Skala ini merupakan suatu skala psikometrik yang biasa diaplikasikan dalam angket dan paling sering digunakan untuk riset yang berupa survei, termasuk dalam penelitian survei deskriptif.

Ekonomi kreatif di Indonesia terus menunjukan peningkatan, salah satunya adalah bisnis startup yang terbukti dari banyaknya startup yang mencapai 992 startup, jumlah tersebut didominasi oleh kawasan Jabodetabek yang berjumlah 522 startup, Sumatera sebanyak 115, Jawa Timur sebanyak 113, Yogyakarta sebanyak 54 dan diikuti oleh kota-kota lainnya. Para startup atau freelancer mengalami kesulitan dalam mencari dan menentukan co-working space yang sesuai dengan keinginan dikarenakan website co-working space yang ada saat ini hanya diperuntukkan untuk co-working space itu sendiri sehingga apabila pengguna ingin membandingkan harga atau fasilitas dengan co-working space yang lain maka pengguna perlu membuka semua website dari co-working space yang lain. Penelitian ini bertujuan untuk membantu startup atau freelancer dalam mencari dan menentukan co-working space yang sesuai dengan kriteria menggunakan metode collaborative filtering. Collaborative Filtering merupakan metode untuk memberikan rekomendasi berdasarkan hasil rating dari pengguna yang lain yang memiliki tingkah laku yang sama. Metode collaborative filtering yang digunakan adalah item-based collaborative filtering. Penelitian ini dimulai dari proses pengumpulan data dengan cara membagikan kuisioner kepada responden, analisa kebutuhan, tahap pengembangan sistem, laporan hasil penelitian, dan pembuatan jurnal. Hasil dari penelitian ini yaitu sebuah website yang terdiri dari kumpulan co-working space yang ada di kawasan Jabodetabek sehingga dapat memudahkan pengguna dalam mencari dan menentukan co-working space dalam satu website.
1,2,3,4-Tetrahydro-1,4,5,8-tetraazaanthracene revisited: properties and structural evidence of aromaticity loss
Authors: Heynderickx Arnault , Nénon Sébastien , Siri Olivier , Lokshin Vladimir , Khodorkovsky Vladimir
Published: August 2019

The synthesis and properties of 1,2,3,4-tetrahydro-1,4,5,8-tetraazaanthracene (THTAA) – a heterocycle involving both >N–H donating and =N– accepting moieties – have been reinvestigated. Unlike previously reported, THTAA is a thermally stable compound that can be re-sublimed at 300–310 °C without decomposition. Controlled introduction of substituents at the nitrogen atoms of THTAA led to variation of its electron donor/acceptor capability that allowed fine-tuning the absorption properties. The propensity of these compounds and a number of its derivatives to form infinite chains involving >N–H···N= and >N–H···Hal−···N+ atoms is demonstrated by X-ray structure analysis. The DFT level optimized and experimental geometry of THTAA and its derivatives show considerable loss of aromaticity within the quinoxaline moiety.

In this project, a nano material based printed patch antenna structure has been integrated with a solar panel without affecting the optical efficiency of the solar panel. The proposed prototype is having the property of both antenna and solar module functionality. A Graphene based CPW fed E-Shaped microstrip patch antenna which has a return loss of -48.43dB at resonant frequency of 2.1GHz which is best suitable for UMTS-2100 Band (2.15GHz – 2.18GHz), GSM (2.15GHz – 2.18GHz) applications is printed on the solar panel using screen printing technique. In this project, conventional copper-based antennas are replaced with graphene-based antennas due to various advantages. In this experiment, the feasibility of material based body mounting antenna structure printing method is analyzed. This proposed design model is best suitable for satellites where antennas occupy one-third of the satellite’s size. By mounting the small printed antennas on the solar panel, the space complexity of the satellite system gets reduced by one-third of its initial dimensions.

Alate gyne of the ant Dolichoderus quadripunctatus (L.) (Hymenoptera, Formicidae) follows foraging trail to aphids
Authors: Czechowski Wojciech , Trigos-Peral Gema , Maák István , Vepsäläinen Kari
Published: August 2019

The first observation of alate gyne of Dolichoderus quadripunctatus (L.) visiting aphids is described. A gyne walked along a foraging trail to the aphid Panaphis juglandis Goeze colony where it imbibed honeydew excreted on the leaf by the aphids, after which it returned to the trail. This recurred during two more days, always a single alate gyne at a time; hence the total number of gynes, one or more, remained open. The phenomenon, hitherto practically unknown in ants, is presented against the background of the biology of the species and discussed in the context of specific environmental circumstances and the colony dynamics.

Two new species, Cylindrolobus motuoensis and C. glabriflorus (Orchidaceae), from Southwestern China and north of Myanmar are described and illustrated with detailed photos. Cylindrolobus motuoensis is morphologically similar to C. gloensis and C. foetidus, but can be distinguished from them by having amplexicaul sterile bracts, dark red floral bracts, white flowers, falcate-lanceolate lateral sepals and central keel of lip running from base to the tip of mid-lobe. Cylindrolobus glabriflorus is similar to C. hegdei and C. tenuicaulis but differs from them by having longer and wider leaves, obovate bracts, and the reddish brown central papillate keel of lip.
Description of two deep-water copepods of the genus Leptotachidia Becker from the northwestern Pacific (Harpacticoida, Pseudotachidiidae)
Authors: Kim Jong Guk , Yu Ok Hwan , Lee Jimin
Published: August 2019

The monospecific genus Leptotachidia Becker, 1974 (Pseudotachidiidae Lang, 1936) was previously known only from the deep Atlantic. Female specimens of two unknown species of this genus were collected from abyssal sediments during an expedition to the northwestern Pacific on board research vessel ISABU (Korea Institute of Ocean Science and Technology) in November 2017. In this paper we describe the females of two new species, L. senariasp. nov. and L. apousiasp. nov. The new species were attributed to the genus Leptotachidia by the combination of the five-segmented female antennule, presence of the Brodskaya organ on the distal antennulary segment, and the second exopodal segments of second to fourth legs without inner setae. An outstanding character of both Pacific species is the reduced armature of thoracic legs in contrast to the type species, L. iberica Becker, 1974. In addition, the setal armature of L. senariasp. nov. and L. apousiasp. nov. is unique within the genus in that the female leg 5 of L. senariasp. nov. has six elements instead of five; and the antennary exopod of L. apousiasp. nov. bears a single seta on the proximal segment instead of two. This is the first record of Leptotachidia from the Pacific. A key to all three species of Leptotachidia is provided.
