Methods to reduce noise level due to environmental changes: A case study in Universitas Gadjah Mada

A sound level mapping in Universitas Gadjah Mada (UGM) was done in 2015. At the end of 2016, there were changes in UGM’s infrastructure and operational management at several areas. This research aims to find the effect of environmental changes toward sound level through sound level mapping. Sound level was recorded by H6 Zoom Recorder at three allocated times, in the morning (6 - 8 AM), at noon (11 AM – 1 PM), and in the afternoon (4 – 6 PM). The sound level mapping in 2017 has shown a decrease of sound level within the range of 2 dBA to 12 dBA. This decrease is indicated in the noise map by the dominance of blue color in the color gradation. The conclusion refers to examples of significant infrastructure and management changes that can reduce sound level such as the usage of ticket or identity card and arrangement of parking area and public space.
A PREDICTOR-CORRECTOR ALGORITHM FOR LINEARLY CONSTRAINED CONVEX OPTIMIZATION

In a recent paper we have introduced a new class of search directions for solving linear optimization (LO) problems. These directions are based on an algebraic equivalent transformation of the nonlinear equation from the system which defines the central path. However, from the implementation point of view predictor-corrector algorithms proved to be the most efficient among the class of interior point methods (IPMs). Therefore, we have defined also other variants of this class of algorithms, for example a weighted path-following algorithm, and a predictor-corrector algorithm for LO problems. Recently, the technique of finding search directions has been applied with success for linearly constrained convex optimization (LCCO), by Zhang, Bai and Wang. In this paper we define a new predictor-corrector algorithm for solving LCCO problems. We obtain new search directions by applying the method of algebraic equivalent transformation in this case too. Polynomial complexity of this algorithm is proved.
A Daisy-Chaining Visual Servoing Approach with Applications in Tracking, Localization, and Mapping

Recent advances in image processing, computational technology and control theory are enabling vision-based control, localization and mapping to become more prevalent in autonomous vehicle applications. Instead of relying solely on a global positioning system (GPS) or inertial measurement units (IMU) for navigation, image-based methods are a promising approach to provide autonomous vehicles with position and orientation (i.e., pose) information. Specifically, rather than obtain an inertial measurement of an autonomous vehicle, vision systems can be used to recast the navigation, localization, control and mapping problems in terms of the image space. Applications involving localization andmapping using camera as a sensor are often described as Visual Simultaneous Localization and Mapping (VSLAM) (Davison et al., 2007; Eustice et al., 2005; Goncalves et al., 2005; Jensfelt et al., 2006; Jung & Lacroix, 2003; Kim & Sukkarieh, 2003; Se et al., 2002), wherein the camera is the main sensor used to estimate the location of a robot in the world, as well as estimate and maintain estimates of surrounding terrain or features. There are many overlapping ways to categorize VSLAM approaches. Some authors (e.g., (Eustice et al., 2005; Jensfelt et al., 2006; Se et al., 2002)) make a distinction between “local VSLAM” and “global VSLAM”. Many VSLAM approaches use probabilistic filters (e.g., extended Kalman filter or particle filter) (Davison et al., 2007; Eustice et al., 2005; Jensfelt et al., 2006; Jung & Lacroix, 2003; Kim & Sukkarieh, 2003), typically estimating a state vector composed of the camera/robot position, orientation and velocity, and the 3D coordinates of visual features in the world frame. An option to a filtered based approach is the use of epipolar geometry (Goncalves et al., 2005; Se et al., 2002). A final possible category are methods that 2
Patterns and Transitions in Substance Use Among Young Swiss Men

This study investigates the potential stages of drug use. Data from the longitudinal Cohort Study on Substance Use Risk Factors were used (N = 5,116). Drug use (alcohol, tobacco, and 16 illicit drugs) over the previous 12 months was assessed at two time points. Patterns and trajectories of drug use were studied using latent transition analysis (LTA). This study’s substantive contributions are twofold. First, the pattern of drug use displayed the well-known sequence of drug involvement (licit drugs to cannabis to other illicit drugs), but with an added distinction between two kinds of illicit drugs (“middle-stage” drugs: uppers, hallucinogens, inhaled drugs; and “final-stage” drugs: heroin, ketamine, GHB/GBL, research chemicals, crystal meth, and spice). Second, subgroup membership was stable over time, as the most likely transition was remaining in the same latent class.

Heuristic Optimization Method for Power System Protection Coordination — An Intelligent Tool for Energy Efficiency Improvement

The electric protection system plays an important safety function for the industrial installa‐ tions. Its main purpose is to detect and clear the occurred faults rapidly and isolate only the faulted part of the system. The electric protection system performances are mainly depending on the type, setting and coordination of protective devices. A good electric protection design and setting improve the energy efficiency of the industrial installations in terms of ensure service continuity, decrease the outage time, prevents the devices damage, and lifetime extension. In this context, the nuclear event that has been occurred at the nuclear power plant of Forsmark in July 2006 it is mainly due to an incorrect tuning of a protective relay [1]. However, due to the complex topology of the modern interconnected power systems and the operation close to its limits, the setting and coordination of protective relays have become a very complex and tedious operation.
Leveraging Competence in the Use of Leveraging Collaborative Tools Competence: Facilitating an Open Architecture Approach to Acquiring Integrated Warfare Systems

A fundamental problem in reaping the benefits of using an Open Architecture (OA) approach to developing integrated warfare systems (IWS) is the requirement for the multiple parties involved to collaborate. This was less of a problem when single vendors managed the entire acquisition life cycle. To take advantage of the potential of OA to use common off the shelf software modules, multiple vendors, greater access and involvement of the acquisition professional and future users of the IWS, collaborative information technology is a necessary ingredient. And, to make collaborative tools useful in the IWS acquisition life cycle, users must leverage their competence with the collaborative tools. To shed light on this requirement, this paper introduces the construct of ‘Collaborative IT Tools Leveraging Competence’ as the ability of various OA work groups involved in the IWS acquisition life cycle to effectively leverage collaborative IT tools to enhance their group performance. Collaborative IT Tools Leveraging Competence is conceptualized as a second-order construct formed by the group’s effective use of the following six key IT functionalities: workspace sharing, conferencing, file sharing, scheduling, chat, and email.Collaborative IT Tools Leveraging Competence is hypothesized to facilitate group performance (process efficiency, project effectiveness, and situational awareness), particularly in intense work environments such as OA acquisition contexts. To enhance an OA work group’s ability to effectively leverage collaborative IT tools, the study proposes a set of enabling factors: customization of the collaborative IT tools, group habits in using collaborative IT tools, the group’s perceived usefulness and ease of use of collaborative IT tools, the group member’s mutual trust, and the degree of environmental intensity.Data from 365 group managers support the proposed structural model with the antecedents and consequences of Collaborative IT Tools Leveraging Competence at different levels of environmental intensity. The paper discusses the study’s contributions of better understanding the nature, antecedents, and consequences of Collaborative IT Tools Leveraging Competence on OA work group performance. Implications for the acquisition of IWS are discussed.
1 Object Models as Heap Invariants

Object models are widely used for describing structural properties of object-oriented programs, but they su er from two problems. First, their semantics is usually unclear. Second, the textual constraints that are often used to annotate diagrams are not integrated with the diagrammatic notation itself. In this paper, we show how to interpret an object model as a heap invariant by translation to a small relational logic. With a few additional shorthands, this logic can be used for textual constraints, so that annotation is just conjunction. Our semantics is simpler than those proposed by others, and accounts for features of the object model that have not been addressed in treatments that focus on more abstract models.
Child restraints for children with additional needs

Transporting children with additional needs is challenging because of the range of physical and cognitive impairments, anthropometry, occupant safety, regulations and usability. Not only does the child restraint system (CRS) need to protect the child in a crash but the carer must also be able to assist the child in and out of the seat. In Australia CRS, except those for children with additional needs, must meet AS/NZS 1754. Unlike, European and United States of American (USA) standards, AS/NZS 1754 has a dynamic side impact test. The objective of the paper is to report on the results of dynamic impact tests conducted on a range of CRS for children with additional needs and identify opportunities for improving the crash performance. A secondary objective was to assess the strength requirements of the top tether anchorage point. Nine CRS models designed for children with additional needs were tested in front and side dynamic impact tests at the New South Wales (NSW) Roads and Maritime Services Crashlab. The tests were conducted according to AS/NZS 1754 specifications. The CRS models were not subjected to full certification or compliance tests. A rebound sled was used and the CRS models were tested with a 36 kg, P10 series Anthropomorphic Test Device (ATD). The frontal impact sled pulse was Δ v = 49 km/h with acceleration 24-34 g and side impact was Δ v = 32 km/h with acceleration 14-20 g. Head and chest resultant acceleration were measured as well as seatbelt and tether forces. CRS models performed relatively well in frontal impacts: peak resultant head accelerations were less than 150 g. In side impacts the average peak headform acceleration across all models was 272 g and the average peak chest acceleration was 178 g, largely because of the lack of ATD restraint and side wings. Those impacts were severe and if they occurred in a real crash would lead to significant head, brain and chest injury. In one test the estimated upper anchorage reached over 10 kN, which is greater than the anchorage strength requirement. There were some breakages or failures of seat and belt components in the tests. Alternative systems to a tether strap for mounting the seat were found to be successful. CRS for children with additional needs performed well in frontal impacts, which reflects the certification of these models to either USA or European standards. The ATD head invariably struck the door panel in the side impact test. The results identified that the CRS models can accommodate and function in frontal tests with the 36 kg crash test dummy, or child, but their performance for heavier occupants is unknown. Further testing with heavier ATDs and a variety of seated postures would be informative. Suitably biofidelic ATDs and child specific injury assessment reference values are study limitations. Dynamic testing of the CRS models was informative in terms of both policy and practice. Improving impact performance and occupant safety is a demanding proposition when the operational context of these systems is considered.
Influence of stand attributes and skid trail area on stand-scale ground flora diversity

Mechanisation is increasingly used in European forest management, but so far, few studies have investigated the combined effects of stand attributes and skid trails on stand-scale ground flora diversity. Our study assessed the effects of stand attributes (age, stand type, basal area) and skid trail area on ground flora diversity in 400 m2 plots in oak forest stands in the northern half of France. We calculated the richness and abundance of ecological groups based on successional status and light preference. We developed and compared generalized linear models and assessed the magnitude of the effects of each variable. At the ecological group level, floristic variations among plots were mostly associated with stand attributes (stand type or basal area). Although we found non-negligible effects of skid trails on all herbaceous groups, these effects disappeared when tree stand attribute effects were incorporated into the statistical models. At the species level, when incorporating stand attribute effects into.
ON THE RADIOLYSIS OF ETHYLENE ICES BY ENERGETIC ELECTRONS AND IMPLICATIONS TO THE EXTRATERRESTRIAL HYDROCARBON CHEMISTRY

The chemical processing of ethylene ices (C2H4) by energetic electrons was investigated at 11 K to simulate the energy transfer processes and synthesis of new molecules induced by secondary electrons generated in the track of galactic cosmic ray particles. A combination of Fourier transform infrared spectrometry (solid state) and quadrupole mass spectrometry (gas phase) resulted in the identification of six hydrocarbon molecules: methane (CH4), the C2 species acetylene (C2H2), ethane (C2H6), the ethyl radical (C2H5), and—for the very first time in ethylene irradiation experiments—the C4 hydrocarbons 1-butene (C4H8) and n-butane (C4H10). By tracing the temporal evolution of the newly formed molecules spectroscopically online and in situ, we were also able to fit the kinetic profiles with a system of coupled differential equations, eventually providing mechanistic information, reaction pathways, and rate constants on the radiolysis of ethylene ices and the inherent formation of smaller (C1) and more complex (C2, C4) hydrocarbons involving carbon–hydrogen bond ruptures, atomic hydrogen addition processes, and radical–radical recombination pathways. We also discuss the implications of these results on the hydrocarbon chemistry on Titan's surface and on ice-coated, methane-bearing interstellar grains as present in cold molecular clouds such as TMC-1.

Enhancement of Dendritic Cell-Based Immunotherapy Using a Small Molecule TGF-beta Receptor Type I Kinase Inhibitor

Abstract : Dendritic cells (DC) have become particularly attractive candidates for cancer immunotherapy due to their potent ability to stimulate antigen specific T cells responses. A number of pre-clinical and clinical studies using tumor antigen-pulsed DCs to treat a variety of malignancies have demonstrated that DC vaccines can elicit measurable cellular anti-tumor immunity. However, despite these encouraging results, DC-based immunotherapy has demonstrated only limited clinical success in the treatment of established tumors. The limited clinical efficacy of existing DC-based cancer vaccines has been attributed in part to suppressive factors produced by the growing tumor, such as transforming growth factor-beta (TGF- ) that has been shown to impair the immunostimulatory capacity of DCs. Therefore, strategies to neutralize the deleterious effects of TGF- may lead to more effective DC-based cancer therapies. HTS466284 and SM16 are potent small molecule TGF- receptor type I (T RI) kinase inhibitors that have been shown to block TGF- signaling by binding to the ATP-binding pocket of this receptor. The hypothesis to be tested is that T RI kinase inhibitor therapy will enhance the efficacy of DC vaccines in the treatment of established murine mammary tumors by rendering DCs resistant to TGF- -mediated immunosuppression. The specific aims of the project are to: 1) Determine the effect of T RI kinase inhibitors on spontaneous tumor metastasis, 2) Evaluate the effect of the combination T RI kinase inhibitors plus DC vaccination on the treatment of primary and metastatic breast cancer, 3) Evaluate the role of immune effector cells in the anti-tumor response following combination therapy with T RI kinase inhibitors and DC vaccines.
PokéStops and Other Spaces of Our Lives: Co-Creation of Social Spatiality Through Consumption of Pokémon GO

The tremendous Pokémon GO craze got the world by surprise in July 2016. Within a couple of days this location-based mobile game gathered a record-breaking number of downloads and transformed the urban environment into a game board by driving people outside their homes to catch imaginary creatures. Combining the physical reality and imagination, this ‘pervasive’ game can be thought of as a new instance of digital virtual consumption (DVC) that could have an enhanced potential to simulate consumer fantasies. While there is a decade of research on how the urban environment can be experienced differently through location-aware technologies, most of it is outdated. Furthermore, little attention has been paid to the full spectrum of social spaces following Lefebvre’s (1991) triad that extends beyond behavior in the observable environment. The aim of this research is to help fill those gaps in understanding how consumers participate in the co-creation of social spaces through the nextgeneration location-based mobile games as a part of their daily lives. Moreover, the goal is to examine how the interface between the ‘real’ and the ‘imaginary’ is being experienced, and what kind of a role gamification plays in the equation. The research problem is approached through qualitative research methods leaning on the philosophical assumptions of interpretivism and phenomenology, that view the world as socially constructed and only understood through one’s ‘being’ in it. The research lies within the field of Consumer Culture Theory (CCT) that explores the dynamic interplay of consumer behavior, environment and culture through contextual, symbolic and experiential aspects of consumption. Consequently, the aim is to describe the phenomenon rather than to find an explanation for it. The research identifies three main themes that together describe the experience of co-creating social spaces through game play. These are labelled as I) trusting the community to fill in the blanks, II) negotiation between spaces of play and duty, and III) making the most of both worlds. Together they draw a picture of a constant struggle between the player community and the game over agency in creating the experience; transformation of spaces and places through the practice of ‘mapping’; uncontrolled switches between spaces of nostalgia and responsibility due to loss of anonymity in the physical reality; and developing alternative game interfaces to optimally integrate the game into players’ everyday spaces. Furthermore, the findings imply an emergence of a new form of gamification, where the core ‘service’ being gamified is, in fact, an individual life as a whole.
ATLASGAL - properties of compact H II regions and their natal clumps

We present a complete sample of molecular clumps containing compact and ultracompact (UC) Hii regions betweenl = 10 ◦ and 60 ◦ and|b|< 1 ◦ , identified by combining the the ATLASGAL sub-mm and CORNISH radio continuum surveys wit h visual examination of archival infrared data. Our sample is complete to optically thin, compact and UC Hii regions driven by a zero age main sequence star of spectral type B0 or earlier embedded within a 1,000 M⊙ clump. In total we identify 213 compact and UC Hii regions, associated with 170 clumps. Unambiguous kinematic distances are derived for these clumps and used to estimate their masses and physical sizes, as well as the Lyman continuum fluxes and sizes of their embedded Hii regions. We find a clear lower envelope for the surface densit y of molecular clumps hosting massive star formation of 0.05 g cm −2 , which is consistent with a similar sample of clumps associated with 6.7 GHz masers. The mass of the most massive embedded stars is closely correlated with the mass of their natal clump. Young B stars appear to be significantly more luminous in the ultraviolet than predicted by current stellar atmosphere models. The properties of clumps associated with compact and UC Hii regions are very similar to those associated with 6.7 GHz methanol masers and we speculate that there is little evolution in the structure of the molecular clumps between these two phases. Finally, we identify a significant peak in the surface density of compact and UC Hii regions associated with the W49A star-forming complex, noting that this complex is truly one of the most massive and intense regions of star formation in the Galaxy.
