PT MNC Televisi Network (Inews) merupakan stasiun tv swasta yang jaringannya menggunakan topologi tree. Penelitian yang telah dilakukan di PT MNC Televisi Network ini akan memaanfatkan fitur fitur yang ada pada router Mikrotik untuk mengatasi permasalahan keamanan jaringan di PT MNC Televisi Network. Dengan berkembangnya zaman akses internet yang disediakan oleh tempat kerja memunculkan masalah terkait penggunaan internet untuk kepentingan pribadi, seperti bermain game online pada saat bekerja atau bermain sosial media. Untuk menangani permasalahan ini peneliti  memblokir trafic – tarfic dari situs2 yang tidak ada hubungan nya dengan kinerja perusahaan itu dengan menggunakan fitur yang ada pada router Mikrotik yaitu filter rule dan filter layer 7 protokol. Dan menambahkan hotspot untuk memonitoring akses wifi yang ada di perusahaan. Dengan di manfaatkannya beberapa fitur yang ada di router Mikrotik bisa membuat jam kerja di PT MNC Televisi Network lebih teratur dan membuat para karyawan tidak lagi bermain game online dan sosial media di jam kerja. Dengan tidak adanya karyawan bermain game online dan sosial media dapat memaksimalkan  efektifitas waktu dalam bekerja Kata kunci: Mikrotik,Filter layer 7 protokol,Filter rule

A reasonable grasping strategy is a prerequisite for the successful grasping of a target, and it is also a basic condition for the wide application of robots. Presently, mainstream grippers on the market are divided into two-finger grippers and three-finger grippers. According to human grasping experience, the stability of three-finger grippers is much better than that of two-finger grippers. Therefore, this paper’s focus is on the three-finger grasping strategy generation method based on the DeepLab V3+ algorithm. DeepLab V3+ uses the atrous convolution kernel and the atrous spatial pyramid pooling (ASPP) architecture based on atrous convolution. The atrous convolution kernel can adjust the field-of-view of the filter layer by changing the convolution rate. In addition, ASPP can effectively capture multi-scale information, based on the parallel connection of multiple convolution rates of atrous convolutional layers, so that the model performs better on multi-scale objects. The article innovatively uses the DeepLab V3+ algorithm to generate the grasp strategy of a target and optimizes the atrous convolution parameter values of ASPP. This study used the Cornell Grasp dataset to train and verify the model. At the same time, a smaller and more complex dataset of 60 was produced according to the actual situation. Upon testing, good experimental results were obtained.

2-Methylisoborneol (MIB) and geosmin produced by blue-green algae were successfully removed in a new gravel filter plant. Small amounts of sludge were sampled from the filter layer and the bacteria able to decompose MIB were isolated from the sludge samples. By-products of the MIB degradation by these bacteria were also investigated. Among these bacteria, efforts were mainly focused on Pseudomonas fluorescens. The components of cell free extracts of this bacterium were studied in order to verify the biological reactions in vitro. 2-Methylenebornane, 2-methyl-2-bornene and isomers of these compounds were found to be a part of the by-products of the MIB degradation in the gravel filter.

Abstract We describe a multianalyte assay system for patient-side use comprising single-use plastic cartridges and a small monitor. Hemoglobin, glucose, and cholesterol can be simultaneously measured in 3 min in an unmeasured volume of blood. The sample is drawn by capillary action into four channels for delivery to assay-specific stacks containing a set of closely apposed layers. The distal layer is a membrane that acts as the optical surface for reflectance optics. For glucose and cholesterol assays, erythrocytes are removed by a fibrous filter layer and oxidase-peroxidase chemical reactions contained in the optical membrane generate a colored product. For hemoglobin measurement, blood is lysed by detergent contained in a porous disk. The amount of color reaching the optical membrane is measured by fiber optics. To ensure fail-safe operation, sensors verify sample sufficiency and degree of hemolysis. The assays perform comparably with laboratory methods.

This study evaluated the partial nitrification performances of two biofilm filters over a synthetic non-ammonium-rich wastewater at a 20°C room temperature under both limited DO (∼2.0 mg/L) and unlimited DO (∼4.0 mg/L) conditions. The two filters were each of 80 cm long and used different biofilm carriers: activated carbon and ceramic granule. Results showed that partial nitrification was accomplished for both filters under the limited DO condition. However, the effluent NO2-N was higher in the ceramic granule filter than in the activated carbon filter, and was less susceptible to the influent COD/N changes. Further investigation into the water phase COD and NH4-N depth profiles and bacteria population within the two filters showed that by putting upper filter layer (upstream) to confront relatively higher influent COD/N ratios, the filtration process naturally put lower filter layers (downstream) relatively more favorable for nitrifying bacteria (ammonia oxidizing bacteria in this study) to prosper, making the filter depth left for nitrification a crucial factor for the effectiveness of nitrification with a filter. The potentially different porous flow velocities of the two filters might be the reason to cause their different partial nitrification performances, with a lower porous flow velocity (the ceramic granule filter) favoring partial nitrification more. In summation, DO, filter depth, and filtration speed should be played together to successfully operate a biofilm filter for partial nitrification.
