Improved OP approach utilising correlated projection and eigenspace processing for robust adaptive beamforming
Authors: Yan Lu , Piao Shengchun , Xu Feng , Yang Juan
Published: August 2019

The capability of orthogonal projection (OP) approach degrades severely in the presence of array model mismatch, especially when the training samples are mixed with the strong desired signal. Therefore, an improved OP robust adaptive beamforming is proposed based on correlated projection and eigenspace processing in wide input signal‐to‐noise ratio to remove the desired signal self‐null effect and improve robustness. In the proposed approach, the interference subspace is constructed combining the correlated projection and eigenspace processing first. Then, the interference‐plus‐noise covariance matrix is accurately reconstructed via super‐resolution spatial spectrum estimator to eliminate desired signal from sample covariance matrix. Subsequently, the desired signal steering vector is corrected applying correlated projection and then the adaptive weighted vector is modified by OP approach. Simulation results demonstrate that the capability of the proposed approach is almost consistently same as the optimal beamformer in many scenarios.

Outcomes of Vascularized Bone Allotransplantation with Surgically Induced Autogenous Angiogenesis in a Large Animal Model: Bone Healing, Remodeling, and Material Properties
Authors: Houben Rudolph H. , Kotsougiani Dimitra , Friedrich Patricia F. , Shin Alexander Y. , Bishop Allen T.
Published: August 2019

Background Bone vascularized composite allotransplantation (VCA) is a possible alternative for the treatment of large bone defects. Clinical application of VCAs is limited by the need for life-long immunosuppression (IS). We report an alternative method to maintain bone allotransplant viability in a large animal model without the need for life-long IS by using autogenous vessel implantation.

Methods Fourteen bone only VCAs were transplanted in a porcine tibia defect model with short-term IS. Two groups were used to evaluate the effect of the implantation of an autogenous arteriovenous (AV)-bundle, therefore the only difference between the groups was the patency of the AV-bundle. We radiographically evaluated bone healing and allogenic pedicle patency. AV-bundle patency and union were evaluated with micro-CT. Bone remodeling was assessed with histomorphometry and material properties were evaluated with axial compression testing and cyclic reference point indentation.

Results Two subjects did not reach the final time point. Twelve tibiae healed proximally, and nine at the distal transplant–bone interface. Bone allotransplants showed their viability in the first 4 to 6 weeks by significant periosteal bridging arising from the transplant and maintained pedicle patency. Bone material properties were not affected by the implantation of an AV-bundle when compared with ligated AV-bundle controls, but diminished compared with normal bone. Significantly higher bone formation rates resulted from the implantation of a patent AV-bundle.

Conclusion New periosteal bone formation and subsequent bone healing result from blood flow through the microsurgically repaired nutrient blood supply, demonstrated by maintained allogenic pedicle patency. The implantation of a patent autogenous AV-bundle has no adverse effect on material properties, but a positive effect on bone remodeling of endosteal surfaces despite thrombosis of the allogenic pedicle. Bone material properties change after transplantation compared with normal bone, although 20-weeks survival time is relatively short for the final evaluation of bone material properties.
Dual Antibiotic Prophylaxis in Total Knee Arthroplasty: Where Do We Stand?

Published: August 2019

The risk of surgical site infection in primary total knee arthroplasty (TKA) has been reduced with the use of prophylactic antibiotics. First or second generation cephalosporins are still recommended as the primary prophylactic choice, but with the rise in the incidence of methicillin-resistant Staphylococcus aureus (MRSA) infections, evidence has emerged in favor of using dual antibiotics including vancomycin. However, it is unclear whether these combinations of antibiotic regimens further reduce postoperative infection rates. As a result, the objective of this review is to summarize the current literature concerning the use of dual prophylactic antibiotics in TKA. The most common dual prophylactic antibiotic combination is cefazolin (C) and vancomycin (V). In general, when comparing the effectiveness of single versus dual antibiotics, conflicting results have been reported. Three studies demonstrated no substantial decrease in overall postoperative infection rates with the use of dual antibiotics when compared with cefazolin alone. One found a significant decrease only in MRSA infection rates when using cefazolin and vancomycin (CV) (0.8% C alone vs. 0.08% CV, p < 0.05). Another investigation evaluated revision TKA patients who had combined cefazolin and vancomycin prophylaxis and showed a significant decline in both overall infection (7.89% [C] vs. 3.13% [CV]) and MRSA infection rates (4.21% [C] vs. 0.89% [CV]; p < 0.05). Concerning the safety profile of dual antibiotics, particular precautions must be adopted with the use of vancomycin because of the risk of acute kidney injury. Instead of vancomycin, an alternate less nephrotoxic antibiotic option might be teicoplanin. Unfortunately, this latter agent is only available outside of the United States. In conclusion, the value of dual antibiotic prophylaxis for the prevention of periprosthetic knee infections remains unclear primarily because all comparative studies performed between dual and single antibiotics have been of low evidence with retrospective designs. Larger multicenter randomized controlled trials are warranted.

Published: August 2019

For patients who qualify, simultaneous bilateral total knee arthroplasty (TKA) is a viable option for the treatment of bilateral symptoms. However, the incidence of chronic obstructive pulmonary disease (COPD) has been steadily rising over the past few decades and may impact those who qualify as candidates for bilateral TKA. As such, the aim of this study was to determine the impact of COPD on postoperative outcomes in patients who receive simultaneous bilateral TKA. A retrospective cohort study was conducted utilizing data provided through the American College of Surgeons National Surgical Quality Improvement Program. All patients who had undergone simultaneous bilateral TKA between 2007 and 2016 were identified and further stratified into groups based upon the COPD status. Incidence of adverse events after TKA in the acute postoperative period was evaluated with univariate and multivariate analyses. COPD was found to be an independent risk factor for the development of major (odds ratio [OR]: 2.5; p = 0.015), renal (OR: 5.1; p = 0.02), and thromboembolic complications (OR: 2.5; p = 0.027). In addition, patients with COPD were at increased risk for having an extended hospital length of stay (LOS; p < 0.001) and development of urinary tract infections (p < 0.001). Patients with COPD are at higher risk for development of overall major complications, as well as renal and thromboembolic complications after simultaneous bilateral TKA. Interestingly, patients were not at increased risk for the development of pulmonary or wound complications. When considering a staged versus simultaneous bilateral TKA, surgeons should be aware of the impact COPD status has on the postoperative complication rate.
Greater Blood Loss in Contemporary Cementless Total Knee Arthroplasty than Cemented Total Knee Arthroplasty despite Tranexamic Acid Use: A Match-Controlled Retrospective Study
Authors: Hood Mark , Dilley Julian E. , Ziemba-Davis Mary , Meneghini R. Michael
Published: August 2019

The purpose of this retrospective study was to assess whether tranexamic acid (TXA) reduces blood loss in cementless total knee arthroplasty (TKA) comparable to levels observed with cemented fixation. After exclusions from 109 consecutive TKAs, 76 cementless knees were matched to 78 cemented knees of identical implant and surgeon. Blood loss with and without TXA was compared. There was no difference between cohorts in sex, age, body mass index, American Society of Anesthesiologists Physical Status classification, or preoperative hemoglobin (p ≥ 0.119). Use of TXA reduced median drain output by only 205 mL in cementless knees compared to 470 mL in cemented knees (p < 0.001). Median drain output per hour was highest in cementless knees without TXA (39.5 mL) followed by cemented knees without TXA (38.2 mL), cementless knees with TXA (28.5 mL), and cemented knees with TXA (12.7 mL; p < 0.001). Hemoglobin drop and total blood loss did not differ between cohorts regardless of TXA use. Cementless fixation in TKA resulted in greater intra-articular blood loss as measured by drain output, despite the use of TXA. Further research is warranted to examine whether a higher TXA dose, TXA delivery method, or the application of bone wax sealant would mitigate blood loss in cementless TKA, and subsequently whether intra-articular blood accumulation resulting in postoperative hemarthrosis affects recovery, function, and clinical outcomes.

Published: August 2019

Extensor mechanism disruption following total knee arthroplasty (TKA) is a devastating complication that causes high failure rates. There is controversy on what is the best way to do an extensor mechanism reconstruction. This study aims to compare both allograft and synthetic reconstructive techniques for success, reoperation, and infection rates and functional outcomes. The search on PubMed, MEDLINE, Embase, BIOSIS, and Cochrane databases was performed on March 15, 2019, using the following keyword groups: (1) “extensor mechanism” and “total knee arthroplasty,” (2) “extensor mechanism” and “knee arthroplasty,” (3) “extensor mechanism” and “revision total knee arthroplasty,” and (4) “extensor mechanism” and “revision knee arthroplasty”. Only studies on extensor mechanism disruption after TKA that included sufficient data to compare these two surgical techniques were included. Meta-analysis was performed with random effect model using the DerSimonian–Laird method. Thirty studies were included. The overall success rate of the reconstruction was 73.3% (95% confidence interval [CI]: 0. 651, 0.814). The success rate of allograft (72.8%, 95% CI: 0.626, 0.829) was not significantly different from synthetic material (78%, 95% CI: 0.707, 0.852, p = 0.416). There was no significant difference in revision rates between allograft (14.2%, 95% CI: 0.095, 0.189) and synthetic material (16%, 95% CI: 0.096, 0.223, p = 0.657). The overall relative risk of infection was 4.301 (95% CI: 1.885, 9.810). There was no significant difference in relative risk of infection between allograft (3.886, 95% CI: 1.269, 11.903) and synthetic material (4.851, 95% CI: 1.433, 16.419, p = 0.793). No statistically significant difference was found in mean postoperative Knee Society score (73.109 [95% CI: 67.296, 78.922] vs. 72.679 [95% CI: 69.184, 76.173], p = 0.901) between allograft and mesh reconstruction groups. There were no significant differences in overall failures, infections, functional outcomes, or revision reconstructions between allograft and synthetic material extensor mechanism reconstructions. Our results demonstrate the difficulty in treating this serious injury, independent of technique, as well as the significant risk for overall failure and infection.
Convective instabilities derived from dissipation of chemical energy
Authors: Simoyi Reuben H.
Published: August 2019

Oxidation reactions of a series of organosulfur compounds by chlorite are excitable, autocatalytic, and exothermic and generate a lateral instability upon being triggered by the autocatalyst. This article reports on the convective instabilities derived from the reaction of chlorite and thiourea in a Hele-Shaw cell. Reagent concentrations used for the development of convective instabilities delivered a temperature jump at the wave front of 2.1 K. The reaction zone was 2 mm and due to normal cooling after the wave front, this induced a spike rather than the standard well-studied front propagation. Localized spatiotemporal patterns develop around the wave front. This exothermic autocatalytic reaction has solutal and thermal contributions to density changes that act in opposite directions due to the existence of a positive isothermal density change in the reaction. The competition between these effects generates thermal plumes. The fascinating feature of this system is the coexistence of plumes and fingering in the same solution as the front propagates through the Hele-Shaw cell. Wave velocities of descending and ascending fronts are oscillatory. Fingers and plumes are generated in alternating frequency as the front propagates. This generates hot and cold spots within the Hele-Shaw cell, and subsequently spatiotemporal inhomogeneities. The small ΔT at the wave front generated thermocapillary convection which competed effectively with thermogravitational forces at low Eötvös numbers. A simplified reaction-diffusion-convection model was derived for the system. Plume formation is heavily dependent on boundary effects from the cell dimensions.
Effects of dynamical and structural modifications on synchronization
Authors: Chen Lijia , Ji Peng , Waxman David , Lin Wei , Kurths Juergen
Published: August 2019

Synchronization is a phenomenon of the collective behavior of coupled oscillators and involves the detailed interplay of the intrinsic frequencies of the oscillators, the underlying topological features of their interaction network, and external perturbations. In this work we investigate, in the strong coupling regime, the response of a system to external perturbations of its natural frequencies and network modifications. Our investigation relies on two performance measures (one for phases and the other for frequencies) and a spectral perturbation analysis. Given strongly localized perturbations in time, corresponding to the dominant eigenmode of the weighted Laplacian matrix of the network, we present a sufficient condition for the maximization of the system’s stability, along with analytical results for the effects of structural perturbations on the system’s response. A number of simulations are conducted to illustrate the theory presented.
Characterization and applications of auto-locked vacuum-sealed diode lasers for precision metrology

We demonstrate the performance characteristics of a new class of vacuum-sealed, autolocking diode laser systems and their applications to precision metrology. The laser is based on adaptations of a design that uses optical feedback from an interference filter and it includes a vacuum-sealed cavity, an interchangeable base-plate, and an autolocking digital controller. A change of the base-plate allows operation at desired wavelengths in the visible and near infrared spectral range, whereas the autolocking ability allows the laser to be tuned and frequency stabilized with respect to atomic, molecular, and solid-state resonances without human intervention using a variety of control algorithms programmed into the same controller. We characterize the frequency stability of this laser system based on the Allan deviation (ADEV) of the beat note and of the lock signal. We find that the ADEV floor of 2 × 10−12 and short-term linewidth of ∼200 kHz are strongly influenced by current noise and vacuum sealing. Reducing the current noise and cavity pressure decreases the ADEV floor and increases the averaging time at which the floor occurs, which is a signature of long-term stability. We also show that evacuating the cavity to ∼1 Torr reduces the range of the correction signal of the feedback loop by approximately one order of magnitude, thereby increasing the lock range of the controller. The long-term stability allows the laser to be incorporated into a commercial gravimeter for accurate measurements of gravitational acceleration at the level of a few parts-per-billion, which are comparable to values obtained with an iodine-stabilized He–Ne laser. The autolocking and pattern-matching features of the controller allow the laser to be tuned and stabilized with respect to a temperature tunable transmission spectrum of a fiber-Bragg grating. This capability may be suitable for the development of a differential absorption LIDAR transmitter that can generate data at both on-line and off-line lock points using a single laser.
Size of a steady disturbance source affects the frequency of a target wave
Authors: Gao Jian , Gu Changgui , Yang Huijie , Weng Tongfeng
Published: August 2019

Controlling the frequency of a target wave is an important issue in the dynamics of pattern formation. A common method for controlling is to apply a local disturbance to the media, such as a periodic disturbance source which is not always valid in practice. In the present study, we proposed a method to control the frequency of a target wave by the application of a steady disturbance. We found that the size of a steady disturbance source affects the frequency of the chemical wave by the numerical simulations of three mathematical models. The simulation results are confirmed by theoretical analysis. Our theory and method shed light in the controlling frequency of the oscillatory media.
Photoluminescence mechanism of phosphorene quantum dots (PQDs) produced by pulsed laser ablation in liquids
Authors: Ge Shuaipeng , Zhang Lisheng , Fang Yan
Published: August 2019

Phosphorene quantum dots (PQDs) with high photoluminescence (PL) quantum yield were fabricated through pulsed laser ablation of black phosphorus in liquids. The PL emission showed excitation wavelength-independent features due to the sufficient passivation by oxygen-containing substituents derived from the ablation-decomposed solvent molecules. There were four peaks in the PL profile showing a multifrequency PL effect, which provided a viable route to investigate the PL mechanism via the detailed structures of the PL profile. The two peaks at shorter wavelengths were attributed to the intrinsic PL transitions. The two peaks at longer wavelengths were assigned to the transitions from the lowest unoccupied molecular orbital to the two-surface states. The positions of the four peaks are redshifted with increasing solvent molecular chain length due to the passivation effect. The intense, excitation wavelength-independent, multifrequency and blue-violet PL emissions indicate the potential application in semiconductor light sources.

Published: August 2019

Intercropping is a farming practice that fights pests and diseases and improves plant growth. The use of plant growth-promoting rhizobacteria (PGPR) strains to boost the yield of intercrops constitutes a promising tool in agricultural practice. This study investigated the impact of single inoculation and co-inoculation with PGPR on plant biomass and phosphorus (P) and nitrogen (N) concentrations under different cropping systems. Two PGPR strains with different traits were selected: PGP13 (Rahnella aquatilis) and PS11 (Pseudomonas sp.). A greenhouse experiment was designed using durum wheat (Triticum durum L.) and faba bean (Vicia faba L.), sole cropped or intercropped, including four inoculation treatments: (i) uninoculated, (ii) inoculated with PS11 (iii) inoculated with PGP13, and (iv) co-inoculated with PS11 + PGP13. Co-inoculation under the intercropping system improved plant dry matter and enhanced bean pod and wheat spike weights to 685.83% and 385.83%, respectively, of the values for uninoculated, intercropped plants. Higher P and N concentrations were detected in intercropped, co-inoculated plants and in bean pods and wheat spikes. The results were then submitted to principal component analysis, showing that treatments with higher biomass and nutrient concentrations were strongly correlated with intercropped, co-inoculated plants.
Chronic disease management and dementia: a qualitative study of knowledge and needs of staff
Authors: Baird Chelsea , Woolford Marta H. , Young Carmel , Winbolt Margaret , Ibrahim Joseph
Published: August 2019

Effective self-management is the cornerstone of chronic disease self-management. However, self-management of chronic disease in patients with comorbid dementia is particularly challenging. It is vital that clinicians, patients and carers work collaboratively to tailor self-management programs to each patient with dementia. This study aimed to identify barriers and facilitators of successful self-management in the context of cognitive impairment in order to optimise the capacity for self-management for persons with dementia (PWD). A qualitative study based on semistructured interviews was conducted in Victoria, Australia. Interviews were conducted with 12 people (employed in the ambulatory and dementia care sectors), representing six health services. Participants identified a healthcare system that is complex, not dementia friendly and not accommodating the needs of PWD who have comorbidities. Individual and systemic barriers contributed to ineffective self-management. Chronic disease support programs do not routinely undertake cognitive assessment or have guidelines for modified management approaches for those with cognitive impairment. Support needs to be long-term and requires a specialised skillset that recognises not only chronic disease management, but also the effect of cognition on self-management. Although formal guidelines are needed, care also needs to be tailored to individual cognitive abilities and deficits.

Diminishing religious cultural heritage of holy Makkah and Medina due to commercialization of the sacred event.
Authors: Qurashi J.
Published: August 2019

This chapter examines the diminishing religious cultural heritage of holy Makkah and Medina in Saudi Arabia due to commercialization of the Hajj. The main focus of this chapter is how mosques and vital historical sites witnessed from the time of the Prophet Muhammad have been demolished, as have Ottoman-era manors and forts, prehistoric wells and stone bridges, including the houses of Sahba (the companions of Prophet Muhammad). The chapter further provides an insight into Hajj and Umrah Ziyara places (religious cultural heritage sites of holy cities), as the majority of Muslim pilgrims during the journey of Hajj and Umrah go for 'Ziyara' to see the religious cultural heritage sites of Makkah and Medina, though Ziyara is not part of the Hajj rites.

Published: August 2019

This chapter explores the everyday socio-spatial changes motivated and mediated by pilgrimage to religious festivals, using as an example the festival in honour of Our Lady of the Abadia (Our Lady of the Abbey), held annually in the city of Romaria, Minas Gerais, Brazil. It is indicated that the act of pilgrimage alters not only the routine of the residents of the destinations where they are held, but also those who participate in the event as tourists, vow-fulfillers, merchants, etc.; and a multiplicity of subjects, concerns and practices cause the pilgrimage to aggregate the sacred and the profane.
Managing catholic churches and sacred sites for protestant visitors to Malta.
Authors: Munro D.
Published: August 2019

This chapter presents a case study of holy places in Malta. A large segment in the recent growth of faith-based tourism to Malta is represented by Protestant visitors. The majority arrive in Malta to discover the places where St Paul has left traces, while a much smaller number visits with the purpose of reconnecting with the Marian traditions which were discarded by Protestantism. One of the current issues is that there is an urgent need to provide a variation of interpretations of Maltese Roman Catholic churches and traditions in order to reach out and connect to the Protestant visitors and to make Malta's religio-cultural heritage relevant to them. A number of matters which need to be considered in product development, management and education are discussed.
The ancient wisdom and motivation of Shams-i Tabrezi or analogy of contemporary systems science and Shams-i Tabrezi ancient wisdom.
Authors: Jakulin T. J.
Published: August 2019

This chapter reviews some of the wise words of Shams-i Tabrezi (the spiritual instructor of the 13th-century Persian poet and Islamic scholar Jalal al-Din Rumi) and presents them in the language and diagrams of modern systems thinking. The wisdom of Shams-i Tabrezi presents the systems thinking of ancient history, which helped Rumi in his transformation to a poet and Anatolian mystic. It is significant that what systems science recognizes, its statements about life and living systems, confirm what Shams-i Tabrezi's wisdom brought to this world. This is evidence that wisdom from the past does not have time limits.

Iron(II) complexes with N2O2 coordinating Schiff base-like equatorial ligand and 1,2-bis(pyridin-2-ylethynyl)benzene as axial pincer ligand
Authors: Schönfeld Sophie , Lochenie Charles , Hörner Gerald , Weber Birgit
Published: August 2019

Three new unique mononuclear iron(II) pincer complexes were synthesized using 1,2-bis(pyridin-2-ylethynyl)benzene as axially coordinating pincer ligand and N2O2 coordinating Schiff base-like equatorial ligands. Magnetic susceptibility measurements reveal that all three complexes remain in the high spin state throughout the entire temperature range investigated. Reasons for this are restraining sterical interactions revealed in the single crystal x-ray structure analysis and extended DFT-computational studies of one of the pincer complexes. Those interactions also lead to the formation of unexpected side products during the synthesis such as a complex with two ethanol molecules as axial ligand, whose x-ray structure was determined.

QuantumATK is an integrated set of atomic-scale modelling tools developed since 2003 by professional software engineers in collaboration with academic researchers. While different aspects and individual modules of the platform have been previously presented, the purpose of this paper is to give a general overview of the platform. The QuantumATK simulation engines enable electronic-structure calculations using density functional theory or tight-binding model Hamiltonians, and also offers bonded or reactive empirical force fields in many different parametrizations. Density functional theory is implemented using either a plane-wave basis or expansion of electronic states in a linear combination of atomic orbitals. The platform includes a long list of advanced modules, including Green’s-function methods for electron transport simulations and surface calculations, first-principles electron-phonon and electron-photon couplings, simulation of atomic-scale heat transport, ion dynamics, spintronics, optical properties of materials, static polarization, and more. Seamless integration of the different simulation engines into a common platform allows for easy combination of different simulation methods into complex workflows. Besides giving a general overview and presenting a number of implementation details not previously published, we also present four different application examples. These are calculations of the phonon-limited mobility of Cu, Ag and Au, electron transport in a gated 2D device, multi-model simulation of lithium ion drift through a battery cathode in an external electric field, and electronic-structure calculations of the composition-dependent band gap of SiGe alloys.
Random walks in non-Poissoinan activity driven temporal networks

Published: August 2019

The interest in non-Markovian dynamics within the complex systems community has recently blossomed, due to a new wealth of time-resolved data pointing out the bursty dynamics of many natural and human interactions, manifested in an inter-event time between consecutive interactions showing a heavy-tailed distribution. In particular, empirical data has shown that the bursty dynamics of temporal networks can have deep consequences on the behavior of the dynamical processes running on top of them. Here, we study the case of random walks, as a paradigm of diffusive processes, unfolding on temporal networks generated by a non-Poissonian activity driven dynamics. We derive analytic expressions for the steady state occupation probability and first passage time distribution in the infinite network size and strong aging limits, showing that the random walk dynamics on non-Markovian networks are fundamentally different from what is observed in Markovian networks. We found a particularly surprising behavior in the limit of diverging average inter-event time, in which the random walker feels the network as homogeneous, even though the activation probability of nodes is heterogeneously distributed. Our results are supported by extensive numerical simulations. We anticipate that our findings may be of interest among the researchers studying non-Markovian dynamics on time-evolving complex topologies.

The nature of the turbulent transport in the edge region of ASDEX Upgrade and JET-ILW deuterium (D) and hydrogen (H) L-mode plasmas is studied using local gyro-kinetic simulations. For both devices the turbulence is found to be dominated by an electron drift-wave destabilized by the high collisionality in the plasma edge and strongly related to the kinetic electron dynamics. The isotope ion mass is found to have an important impact on the edge turbulence. In linear simulations, wider eigenfunctions of the electrostatic potential with a lower isotope mass translate in a lower threshold in the normalized electron temperature gradient and in a higher linear growth rate. In non-linear simulations, higher turbulent transport is predicted with a lower isotope mass. The effect of the isotope mass on the turbulent fluxes is enhanced by electromagnetic effects, which are found to be important in non-linear simulations. Remarkably, when considering all the effects in the non-linear simulations and the experimental uncertainties, the predicted fluxes can reproduce the experimental fluxes and their behavior with the isotope mass.

Job promotion is the best action of a company to improve the progress of the company itself, thus it must be done objectively and responsibly respectfully. There are a number of benchmarks for carrying out the promotion process which as a whole can be recognized as an honorable action for someone selected through this promotion process, in this study called criteria, the benchmark consists of seven criteria that can represent strength that can be recognized based on company provisions. This rule has two understandings that are interpreted differently and are quite difficult for mathematical calculation processes. For criteria that are meaningful and related to time have the meaning that the weight of the smallest value is the best, or different meanings that bear the weight of the greatest value are the best. For this promotion process, a combination of the Analytic Hierarchy Process (AHP) method and the VIKOR index elimination system is used, both of which have far different functions, namely AHP is intended to determine the preference weighting scale while VIKOR is intended to determine the ranking of each alternative over the alternative. The decision on the outcome of the best promotion is the fifth employee (K5) with a score index of 0.00 and followed sequentially (K2), (K3), (K1), (K4) sequentially with a score index of 0.62; 0.66; 0.75 and 0.93. This result is used as a benchmark for the best decisions.
Classification of Milk Fish Quality using Fuzzy K-Nearest Neighbor Method Based on Form Descriptor and Co-Occurrence Matrix
Authors: Sutaji Deni , Dijaya Rohman
Published: August 2019

Milkfish is a type of fish that lives in fresh water. Caught milkfish will be sorted at fish processing companies and will be a variety of milk, fish products in the form of cooked or in the form of fresh fish. A manual separation system of milkfish often experiences errors in the separation of fish species so that it takes a long time in the process of separating these types of fish, because it is very dependent on the skills of employees or employees. Errors in the separation of milkfish based on their size will cause a failure in the production section because it will affect the difference in the maturity level of a product, which will result in errors in the process of cooking the fish, which has an impact on the loss in the financial sector of a company. In order to maintain the quality of milkfish and speed up the sorting of milkfish, it is necessary to create a system that can help workers and employers in distinguishing the quality of milkfish based on their size. So the writer will create a system “Image Quality Classification of Milkfish Using Fuzzy K-Nearest Neighbor Method Based on Descriptors of Forms and Co-occurrence Testing was carried out using 45 images of milk fish. From the test results based on the shape feature and the co-assurance matrix produces 100%, which is in accordance with the form feature requirements and the co-insurance matrix as the reference data.
Fixed Order Interval Model for Multi Item Single Supplier Considering Lifetime and Minimum Order Quantity

Published: August 2019

This paper presents of a material procurement model for multi-item single supplier material considering the life time and minimum order quantity. Procurement of several types of material (multi items) is carried out simultaneously from one supplier with consideration of the savings in ordering costs. The problem is when the order must be performed simultaneously, and how much material must be ordered to obtain a minimum total cost. The cost variables considered in this model are purchase costs, ordering costs, storage costs, and expired cost. This modeling was inspired by a real case found in a manufacturing company located in Bandung. Facts in the field show there were frequently waste due to material has expired. This happens because the material age is relatively short, while the order size must follow the minimum quantity stipulated by the vendor or supplier. Until now the authors have not found a model which fits to this case. However the authors found several articles which have similarities to, and the authors made it as comparison. The developed model departs from the basic model which be developed by several experts. The author modified little bit by adding the cost variable such as the expired cost. Then the authors engaged the model with completely algorithm. This model is a continuation of the single item model developed by Arifin D, and Charisma C, which has been presented and published in the IEOM Conference Proceedings 2018.
