    Description

    Report Filter Definitions and Guidance Please note that all filter options are present in the dataset. For example, if you are looking at a dataset and a state is missing, it means there is no data for the year selected in that state - it does not use a list of all US states. Also note that if the data table disappears, there is no data available for the filter selections made.

    Description

    The global privacy filter market is experiencing robust growth, driven by increasing concerns over data breaches and the need for enhanced digital security in both corporate and personal settings. The market, estimated at $2.5 billion in 2025, is projected to maintain a healthy Compound Annual Growth Rate (CAGR) of 7% through 2033, reaching an estimated market value of approximately $4.2 billion. This expansion is fueled by several key trends, including the proliferation of remote work, increasing adoption of BYOD (Bring Your Own Device) policies, and stringent data privacy regulations like GDPR and CCPA. Major players like 3M, V7, HP, Dell, Fellowes, Targus, Kensington, and Zagg are actively contributing to market growth through innovation in filter technology, offering a wide range of products catering to various screen sizes and devices. However, market growth is not without its challenges. Price sensitivity among consumers and the availability of alternative solutions, such as software-based privacy solutions, pose potential restraints. The market segmentation is diverse, encompassing different filter types (magnetic, adhesive, clip-on), screen sizes, and device compatibility. Regional growth varies, with North America and Europe currently holding significant market share due to higher awareness of data privacy and higher disposable incomes. Nevertheless, developing economies in Asia-Pacific are expected to witness significant growth in the coming years, driven by increasing internet penetration and rising adoption of digital technologies. The ongoing evolution of display technologies, such as foldable and curved screens, presents both opportunities and challenges for privacy filter manufacturers, requiring continuous adaptation and innovation to maintain market relevance and competitiveness.

    Description

    A list of two data frames that summarize the performance of Aqua Aerobic Systems, Inc. cloth filters for primary wastewater treatment at BC Labs. Cloth filters should treat more wastewater to a higher quality with a smaller physical footprint than a traditional primary clarifier. The first data frame contains laboratory data measuring influent and effluent water quality for both the primary cloth filter and primary clarifier. Lab samples were taken at an irregular frequency from April 6, 2017 to November 5, 2019, but samples for the cloth filter were more consistent and frequent than those taken for the primary clarifier. The second data frame contains daily operational averages of online sensor data for the primary cloth filter from January 1, 2019 to January 1, 2020, which includes process control variables. The goals were to (1) determine whether the cloth filter removes more solids and contaminants than the clarifier and (2) investigate how to improve the cloth filter performance.

    Description

    In this paper, we propose a novel approach to reduce the noise in Synthetic Aperture Radar (SAR) images using particle filters. Interpretation of SAR images is a difficult problem, since they are contaminated with a multiplicative noise, which is known as the “Speckle Noise”. In literature, the general approach for removing the speckle is to use the local statistics, which are computed in a square window. Here, we propose to use particle filters, which is a sequential Bayesian technique. The proposed method also uses the local statistics to denoise the images. Since this is a Bayesian approach, the computed statistics of the window can be exploited as a priori information. Moreover, particle filters are sequential methods, which are more appropriate to handle the heterogeneous structure of the image. Computer simulations show that the proposed method provides better edge-preserving results with satisfactory speckle removal, when compared to the results obtained by Gamma Maximum a posteriori (MAP) filter.

    Description

    This polygon shapefile represents filters used with I-Site Studio software to filter ground observations collected by terrestrial laser scanner (TLS) survey in Grapevine Canyon near Scotty's Castle, Death Valley National Park, from July 12-14, 2016. Filters were used to remove extraneous data from features such as vegetation, fences, power lines, and atmospheric interference. The resulting points were used to produce a digital terrain model of the area (GrapevineCanyon_TIN.zip in this data release).

    Description

    Spatio-temporal datasets are rapidly growing in size. For example, environmental variables are measured with increasing resolution by increasing numbers of automated sensors mounted on satellites and aircraft. Using such data, which are typically noisy and incomplete, the goal is to obtain complete maps of the spatio-temporal process, together with uncertainty quantification. We focus here on real-time filtering inference in linear Gaussian state-space models. At each time point, the state is a spatial field evaluated on a very large spatial grid, making exact inference using the Kalman filter computationally infeasible. Instead, we propose a multi-resolution filter (MRF), a highly scalable and fully probabilistic filtering method that resolves spatial features at all scales. We prove that the MRF matrices exhibit a particular block-sparse multi-resolution structure that is preserved under filtering operations through time. We describe connections to existing methods, including hierarchical matrices from numerical mathematics. We also discuss inference on time-varying parameters using an approximate Rao-Blackwellized particle filter, in which the integrated likelihood is computed using the MRF. Using a simulation study and a real satellite-data application, we show that the MRF strongly outperforms competing approaches. Supplementary materials include Python code for reproducing the simulations, some detailed properties of the MRF and auxiliary theoretical results.

Description

Report Filter Definitions and Guidance Please note that all filter options are present in the dataset. For example, if you are looking at a dataset and a state is missing, it means there is no data for the year selected in that state - it does not use a list of all US states. Also note that if the data table disappears, there is no data available for the filter selections made.
