iSafe - Authorization using Typing Rhythm: A Survey

– With the ever increasing demand for more secure access control in many of today’s security applications, traditional methods such as PINs[1][7], tokens, or passwords fail to keep up with the challenges presented because they can be lost or stolen. On the other hand, biometrics based on “who” the person is or “how” the person behaves presents a significant security advancement to meet these new challenges. Among them, keystroke dynamics provide a natural choice for secure “password-free” computer access Keystroke dynamics refer to the habitual patterns or rhythms an individual exhibits while typing on a keyboard input device. These rhythms and patterns of tapping are distinctive in the same way as a person’s handwriting or signature, due to their similar governing neurophysiological mechanism. Here an attempt is made to develop a robust system to identify the users. The idea is to add three factors of authentication by entering the correct password, cued click point concept, and identifying the users typing pattern.
Exploring a Performative Approach to Felting Wool An Autoethnography for Two?

This text treats the author’s imagined research design based on her artistic research and pedagogical views. She tentatively call this arts based approach an autoethnography for two. The starting point of this approach is her critical view on a certain confine pedagogy in teacher education and a desire to walk away from being the object of a research project. She aspires for a teacher education in the arts subject that recognizes and values the working process as a significant part of creative processes, also within school contexts. Furthermore, she wants to join the multiple identities that compose the identity of many actors in school settings, which comprise the artist, the teacher and the researcher. The ambition of this text is to articulate a plausible research design that can inspire others in their quest when embarking with arts based research in their artistic work and/or educational work. Her research in this text relates to her re-turning to the ancestral technique of hand felting wool. She questions and approaches this traditional technique by adopting a performative approach to the making. This approach suggests that making sense (as knowledge production) is intimately connected to the making (of felting wool in this case). By inviting peers in an autoethnography for two, to share impressions and reflections, this research design can elicit diffractively, a working process.
Comparing reaction time sequences from human participants and computational models

This paper addresses the question how to compare reaction times computed by a computational model of speech comprehension with observed reaction times by participants. The question is based on the observation that reaction time sequences substantially differ per participant, which raises the issue of how exactly the model is to be assessed. Part of the variation in reaction time sequences is caused by the so-called local speed: the current reaction time correlates to some extent with a number of previous reaction times, due to slowly varying variations in attention, fatigue etc. This paper proposes a method, based on time series analysis, to filter the observed reaction times in order to separate the local speed effects. Results show that after such filtering the between-participant correlations increase as well as the average correlation between participant and model increases. The presented technique provides insights into relevant aspects that are to be taken into account when comparing reaction time sequences. Index Terms: reaction times, local speed, participant-model comparison, computational modeling, spoken word recognition

Concept of Human-Robot-Interaction Control for Ortheses with Pneumatic Soft- Actuators

This paper presents a concept for human-robot-interaction (HRI) for controlling robots with compliant pneumatic soft-actuators which are directly attached to the human body. For comfort and safety backdrivability of this type of actuators is beneficial and they are well suitable to design rehabilitation robots. As application example for training of activities of daily living (ADL) sit-to-stand tasks are used, taking conventional treatment in neurology as reference. The focus is on stroke patients with a target group suffering from hemiplegia and paralysis in one half of the body. Based on master-slave position control movements form the fit leg are transferred to the affected led using a 2 degrees of freedom (DOF) exoskeleton robot as testbed. Furthermore the wearer of the robot has the possibility to adjust support for stabilizing the knee joint manually.
Construction Contract Conversion: An Approach to Resolve Disputes

Abstract A construction contract is a mechanism to bind a project owner and a contractor in a legal agreement to construct a project against a designated monitory consideration. However, projects are usually assembled over a long period with high uncertainty and complexity. Under such a dynamic business transaction, current static contracts fail to arrange for an appropriate and stable transaction. This paper reveals, through a questionnaire survey that was sent to all grade1 and 2 contractors and all owners in Riyadh-Saudi Arabia, the most common construction contracts in Saudi Arabia and the use, causes and benefits of contract conversion. The lump sum and the unit price are the most dominant type of contracts. Owners who select the former convert them during construction to unit price contracts leading to considerable benefits to contract parties including successful project completion with negligible disputes and better relationship. Owners are advised to include a clause in the construction contract to give them the privilege, not the obligation to convert the contract from one type to another.
Trends of Forgiveness in Adolescents who have experienced Emotional Violence by Parents

This research was conducted to obtain an empirical picture of forgiveness in adolescents who experience emotional abuse by parents and its implications for guidance and counseling. This study used a quantitative approach with a descriptive method. The sample used in this study were 39 adolescents who experienced emotional violence in SMP Negeri 14 Bandung Academic Year 2018/2019 during class of eight.

The research findings show that forgiveness in adolescents who experience emotional abuse by parents tends to be in the moderate category. The implication of this study is the development of a mentoring and personal-social counseling program to increase forgiveness in adolescents who experience emotional violence by parents.
Over-expression of the hybrid aspen homeobox PttKN1 gene in red leaf beet induced altered coloration of leaves.

PttKN1 ( Populus tremula A— tremuloides KNOTTED1 ) gene belongs to the KNOXI gene family . It plays an important role in plant development, typically in meristem initiation, maintenance and organogenesis, and potentially in plant coloration. To investigate the gene functions further, it was introduced into red leaf beet by the floral dip method mediated via Agrobacterium tumefaciens . The transformants demonstrated typical phenotypes as with other PttKN1 transformants. These alterations were very different from the morphology of the wild type. Among them , morphological modification of changed color throughout the entire plant from claret of wild type to yellowish green was the highlight in those transgenic PttKN1 -beet plants. The result of spraying selection showed that the PttKN1 -beet plants had kanamycin resistance. PCR assay of the 35S-Promoter, NPTII and PttKN1 gene, PCR-Southern analysis of the NPTII and PttKN1 gene showed that the foreign PttKN1 gene had successfully integrated into the genome of beet plant. Furthermore, the results of RT-PCR analysis showed that the gene was ectopic expressed in transgenic plants. These data suggested that there is a correlation between the ectopic expression of PttKN1 gene and morphological alterations of beet plants. Pigment content assay showed that betaxanthins concentrations shared little difference between wild type and transgenic lines, while betacyanins content in transgenic plants was sharply decreased, indicating that the altered plant coloration of the transgenic beet plants may be caused by the changed betacyanins content. The tyrosinase study suggested that the sharply decreased of betacyanins content in transgenic plants was caused via the decreased tyrosinase level. Therefore, the reason for the altered plant coloration may be due to partial inhibition of betacyanin biosynthesis that was induced via the pleiotropic roles of PttKN1 gene .

Director selection in agricultural cooperatives—The process and the roles in the Finnish context

Abstract Director selection is linked with contradictory board roles which call for the need of multiple approaches. In cooperatives, which are member- and user-driven rather than profit-driven, this approach is essential. The aim of this study is to analyze director selection in agricultural cooperatives by using a qualitative approach and hence, contribute to theory development. The results indicate that the director selection process and roles contain several paradox issues in two dimensions: administrative culture as well as the roles and authority of important actors. The paper contributes to the understanding of (1) mechanisms and relationships inherent in the process of director selection in agricultural cooperatives (2) the administrative culture as well as the roles and authority of the actors in the process and (3) paradoxes which help us to understand tensions in director selection under the requirement of fulfilling both the performance task and the conformance task. The paper discusses the results against the current board theories and suggests a new paradox dimension. It is suggested that director selection should be studied further from the perspectives of (1) implications of the use of authority and (2) the implications of the administrative culture.
Sacred Spaces: The e-Journal of the American Association of Pastoral Counselors (2014), vol.6 A Cloud of Unknowing: Articulations of Identity and Faith in Younger Adolescents

Younger adolescents struggle to recruit and retain adult mentoring and engagement across the many institutions in which they participate, creating a potential dearth of support critical to the development of mature identity and faith. Because their bodies and social roles are in flux, as well as their capacity to interpret themselves socially and existentially to those around them, younger adolescent expressions of self are often variable. However, mature conventions of selfhood require the capacity to articulate one’s self in a recognizable and consistent fashion, causing many adults to be uncomfortable and impatient in the face of younger adolescents’ unpredictability. Persons who hope to provide support to younger adolescents require the capacity and desire to be a consistent relational presence despite the unknowability of the middle school self.
A Survey on Big Data and Hadoop

- The term ‘Big Data’ describes innovative techniques and technologies to capture, store, distribute, manage and analyze larger-sized datasets with high-velocity and different structures. Big data can be structured, unstructured or semi-structured, resulting in incapability of conventional data management methods. Data is generated from various different sources and can arrive in the system at various rates. In order to process these large amounts of data in an inexpensive and efficient way, parallelism is used. Big Data is a data whose scale, diversity, and complexity require new architecture, techniques, algorithms, and analytics to manage it and extract value and hidden knowledge from it. Hadoop is the core platform for structuring Big Data, and solves the problem of making it useful for analytics purposes. Hadoop is an open source software project that enables the distributed processing of large data sets across clusters of commodity servers. H adoop File System was developed using distributed file system design, HDFS is highly fault tolerant and designed using low-cost hardware. It is designed to scale up from a single server to thousands of machines, with a very high degree of fault tolerance.
ESTIMATED IMPORT DEMAND FUNCATION FOR PAKISTAN: A DISAGGREGATED ANALYSIS

The theme of the study was to estimate the elasticity of aggregated and selected disaggregated import demand function with relative prices and income for Pakistan from 1982 to 2011 on annual data. The most effective estimation tool was used (Auto-regressive Distributed Lag ARDL) by employing the Bounds Test method and Error Correction Modeling (ECM) techniques. The Un-restricted Error Correction Model (UECM) ARDL to calculate the long run elasticity of import while the short term dynamics is estimated through restricted ECM. In this research, aggregated import demand and disaggregated import demand commodities groups were made. Petroleum, Chemical, Manufacturing Goods and Machinery and Transport Groups are response variables whereas Gross Domestic Product (GDP) and Relative Prices variables are treated as explanatory variables. The disaggregated analysis of above mentioned various commodities groups are conducted in order to identify the fundamental drivers of import demand and to design fiscal and economic policy accordingly. The results indicated that at aggregated level, import demand with respective relative prices is elastic whereas it is inelastic with income in the long run. At disaggregated level, import demand with relative prices of machinery and transport group is elastic only while it is inelastic with income level in all selected disaggregated imports demand in long run. Furthermore, all import demand models are statistically significant having expected association and are stable in long run. In sort run aggregate import demand, petroleum and chemical groups are statistically significant while manufacturing goods, machinery and transport groups are insignificant. Furthermore all alternate hypotheses were accepted.
MITIGATION OF SALINITY STRESS AND ALTERNARIA LEAF SPOT DISEASEIN FABA BEAN BY NICOTINAMIDE

Vicia faba is one of the most important leguminous crops, where it represents a major constituent of daily food for most of populations. The present investigation aimed to study the influence of salinity stress and Alternaria leaf spot on faba bean cultivars during thresholds of nicotinamide and fungicide Tridex-80.Obtained data pointed out that both of nicotinamide and Tridex-80 had inhibitory effect against Alternaria leaf spot pathogen in vitro. The germination percentage decreased significantly with increasing soil salinity. However, increasing percentage of germination was associated with nicotinamide and Tridex80%. Interestingly, low threshold of nicotinamide (200mg/l) was superior to another one, where affected on plant growth parameters. Both of disease incidence and severity of Alternaria leaf spot in faba bean were significantly decreased in the presence of thresholds of nicotinamide and Tridex-80. Likewise, increasing of chlorophyll a, b, polysaccharides, free amino acids, proline and antioxidant enzymes as response to nicotinamide thresholds. Ultimately, the yield productivity was consequently increased as the nicotinamide and Tridex-80 doses against salinity stress and Alternaria leaf spot disease.
Top Quark Properties at the Tevatron

In the Standard Model of Particle Physics, the top quark is the “up-type” quark of the third generation, weak isospin partner of the bottom quark, with charge Q = +2/3. After the top quark discovery in 1995 at the Tevatron by both the CDF and DØ Collaborations [1, 2], many measurements have been performed to map its properties. Being the most massive fundamental particle known up to date, it is the dominant contributor to radiative corrections for many Standard Model processes. The top quark has also very large coupling to the not yet observed Higgs boson and may be related to the electroweak symmetry breaking mechanism, and thus sensitive to new physics, which could be constrained by measuring its production and decay properties. Thanks to the increasing quantity of data delivered by the Tevatron, amounting to more than 5 fb−1 to date, precision measurements on top quark physics can be performed, allowing to improve the understanding of the observed particle and its role within the Standard Model. This paper reports the most recent results of measurements of top quark properties performed by both the CDF and DØ Collaborations, in particular in the areas of top intrinsic properties and decay, providing a short summary of a few of them. In pp̄ collisions at √ s = 1.96 TeV top quarks are mainly produced in pairs through quark-antiquark annihilation (85%) or gluon fusion (15%). Since within the Standard Model the top quark decays almost exclusively to a W boson and a b quark, the top

A Review on Ontology Development Methodologies for Developing Ontological Knowledge Representation Systems for various Domains

—The success of machine represented web known as semantic web largely hinges on ontologies. Ontology is a data modeling technique for structured data repository premised on collection of concepts with their semantic relationships and constraints on domain. There are existing methodologies to aid ontology development process. However, there is no single correct ontology design methodology. Therefore, this paper aims to present a review on existing ontology development approaches for different domains with the goal of identifying individual methodology’s weakness and suggests for hybridization in order to strengthen ontology development in terms of its content and constructions correctness. The analysis and comparison of the review were carried out by considering these criteria but not limited to: activities of each method, the initial domain of the methodology, ontology created from scratch or reuse, frequently used ontology management tools based on literature, subject granularity, and usage across different platforms. This review based on the literature showed some approaches that exhibit the required principles of ontology engineering in
The role of hepatocyte growth factor/scatter factor in hepatoblastoma and hepatocellular carcinoma progression

Hepatocyte growth factor/scatter factor (HGF/SF) is a ubiquitously expressed molecule that elicits pleiotropic functions on epithelial cells, including mitogenic, motogenic, differentiating, angiogenic, and morphogenic effects. The receptor for HGF/SF is c-Met, a product of the proto-oncogene c-met, which is abundantly expressed in many tumors, rendering them highly receptive for HGF/SF signals. In hepatoblastoma (HB) and hepatocellular carcinoma (HCC), a high relapse incidence and post-operative residual tumor growth can be detected, when the serum levels of HGF/SF are markedly elevated, suggesting a link between this molecule and tumor malignancy. Although HB and HCC are two distinct subtypes of primary tumors arising from liver parenchymal cells and thus differ by many histo-clinical characteristics, comparative analysis of the impact of HGF/SF on these tumors may provide some clues on the oncogenic pathways leading to liver tumor progression. The results of this study demonstrate that HGF/SF mediates cytoprotective functions against the apoptotic inducers cisplatin, camptothecin, and starvation in a phosphoinositide 3-kinase (PI3K)dependent manner, thereby contributing to chemotherapy resistance. Differences between HB and HCC cells regarding the sensitivity towards HGF/SF and HGF/SFstimulated cellular responses were observed and are associated with c-Met expression. Furthermore, our experiments demonstrate that HGF/SF is a potent inducer of cell scattering and migration. HGF/SF triggers scattering of epithelial cells by upregulating the expression of Snail, a transcriptional repressor involved in epithelial-mesenchymal transition (EMT). Snail, which represses for example the expression of E-cadherin and claudin-3, is required for HGF/SF-induced cell scattering, since shRNA-mediated ablation of Snail expression prevents this process. HGF/SF-induced upregulation of Snail transcription involves activation of the mitogen-activated protein kinase (MAPK) pathway and requires the activity of early growth response factor (Egr)-1. Thus, HGF/SF plays a critical role in cell scattering, migration, and invasion. Together, these findings highlight the importance of HGF/SF in tumor cell survival and tumor progression and suggest that it should be considered as a candidate for therapeutic strategies.
