The building sector accounts for 39.7% of global energy consumption and 42% of carbon emissions, highlighting the need for improved energy efficiency. While data-driven energy benchmarking is vital for conservation, current approaches face key challenges: limited datasets, suboptimal prediction algorithms, and inadequate scoring systems. This study proposes an AI-driven benchmarking framework using a dataset from 13 U.S. cities across nine climate zones. 12 state-of-the-art algorithms are evaluated for energy prediction accuracy across building types and climates. Based on the evaluations, a Multi-algorithm Prediction (MAP) framework is introduced, which dynamically selects the most suitable model for energy prediction according to specific building types and climate zones. Moreover, to enhance the scoring system, this study refines peer-grouping by applying K-Means clustering using essential building attributes. It implements a dual-factor scoring system balancing both site and source energy performance. Results show that algorithm performance varies significantly by building type and climate zone. Using MAP for energy prediction can achieve 9.33-63.27% greater accuracy compared to single-model predictions. The modified scoring results are sensitive to the value of the balancing factor, particularly for buildings with mid-range performance. A balancing factor of 0.5 yields statistically balanced outcomes. This study enhances the reliability and effectiveness of building benchmarking by (1) improving energy prediction through MAP based on a comprehensive dataset, (2) enhancing peer-group reliability, and (3) offering insights into the impacts of integrating site and source energy performance in scoring.

The computation burden of intensive numerical real-time algorithms is a problem encountered in robotics and many other fields. A cost-effective solution for the implementation of these algorithms requires knowledge of computer architecture, compiler technology and algorithms. A cost-effective numeric processing methodology using a combined hardware-software approach and taking advantage of logic programming tools is presented. The methodology is based on optimizing the numerical calculation process of the algorithm. It also enables the specification of hardware resources. The process uses a rule-based-system (RBS) implemented in the logic programming language Prolog to automatically reduce the number of operations in the numerical execution of the algorithm and optimizes the use of hardware resources. The methodology provides a solution for the problems of handshake overhead and algorithm translation efficiency. The Direct Kinematics Solution (DKS), a robot arm control algorithm, is presented as a case study to illustrate the methodology. The proposed methodology has a general potential which can be extended to the optimization or implementation of different algorithms.

Optical Coherence Tomography (OCT) is rapidly becoming the method of choice for assessing arterial wall pathology in vivo. Atherosclerotic plaques can be diagnosed with high accuracy, including measurement of the thickness of fibrous caps, permitting an assessment of the risk of rupture. While the OCT image presents morphological information in highly resolved detail, it relies on interpretation of the images by trained readers for the identification of vessel wall components and tissue type. We developed a framework to aid the recognition of these atherosclerotic plaque constituents, based on the optical attenuation coefficient of the tissue. Based on a single-scattering model and using the point spread functions of individually characterized imaging catheters, several parameters need to be set in the analysis that may influence the results. Here, we present a simulation study used to optimize these parameters.

The precise time interval measurement is the key in many applications. Recent-developed linear optical sampling method has pushed the time interval measurement to the femtosecond region. However, technique noise limits the precision improvements. To further optimize the precision of the time interval measurement scheme based on linear optical sampling, here we give an algorithm method to optimize the effective low-noise region of waveform and achieve the measurement stability of 22.9 fs.

In the article we consider, on the example of development of a relational database (RDB) information system for Tatneft oil and gas company, an approach to organization of effective search in large arrays of heterogeneous data, satisfying the following essential requirements. On the one hand, the data is integrated at the semantic level, i.e. the system supports the presentation of data, describing its semantic properties within an unified subject domain ontology. Accordingly, end user's request are formulated exclusively in the subject domain terminology. On the other hand, the system generates unregulated SQL-queries, i.e. the full text of possible SQL-queries, not just values of particular parameters, predefined by the system developers. Considered approach includes both the possibilities of increasing the reactivity of the universal SQL queries generation scheme as well as more specific optimization possibilities, arising from the particular system usage context.

Evaluation and optimization, with an ever increasing variety of material, are getting more and more time-consuming tasks in video algorithm development. An additional difficulty in moving video is that frame-by-frame perceived performance can significantly differ from real-time perceived performance. This paper proposes a way to handle this difficulty in a more systematic and objective way than with usual long tuning procedures. We take the example of interpolation algorithms where variations of sharpness or contrast look annoying in real-time whereas the frame-by-frame performance looks well acceptable. These variations are analyzed to get an objective measure for the real-time annoyance. We show that the reason for the problem is that most interpolation algorithms are optimized across intraframe criteria ignoring that the achievable intrinsic performance may vary from frame to frame. Our method is thus based on interframe optimization taking into account the measured annoyance. The optimization criteria are steered frame by frame depending on the achievable performance of the current interpolation and the achieved performance in previous frames. Our policy can be described as "better be good all time than very good from time to time". The advantage is that it is automatically controlled by the compromise wished in the given application.

Bi-cubic interpolation algorithm is commonly used in image scaling, but traditional cubic interpolation has its own shortcomings such as complicated computation, long computational time and so on. For these problems, the paper studies traditional cubic kernel function and proposes an optimized algorithm with adjustable coefficients. This algorithm utilizes an modifying coefficient lambda to amend the coefficients in the kernel function, which helps the scaling system choose best algorithm with different images. Then, the superiority is verified by MATLAB simulation and the optimized algorithm is applied to the image scaling engine called scaler through the verification in FPGA.

The transformation of natural land cover to urban areas severely alters the hydrologic flow regime of watersheds. The negative impacts include the increase of surface runoff and decrease of infiltration rates, which can result in more frequent and intense flood events and the reduction of groundwater recharge. Low Impact Developments (LIDs) are strategies designed to better mimic the natural flow regime by promoting higher infiltration and the treatment of stormwater. Examples of LID structures are bio-gardens, green roofs, bio-swales and pervious pavements. While the expansion of LIDs in urban catchments would be desirable, retrofitting large urban watersheds with LIDs can be cost prohibitive. This study combines hydrologic simulation with a Multi-Objective Evolutionary algorithm (MOEA) to find solutions in terms of LID design and location in urban catchments that maximize the environmental benefits and characterize the tradeoffs between LID performance indicators and costs. The solutions are evaluated in terms of costs, peak flow, and the Hydrologic Footprint Residence (HFR). The HFR is a new metric designed to quantify the impacts of urbanization in the hydrologic regime by representing the dynamics of inundated areas and residence time of flood waves. The results provide a basis for better stormwater management and planning because tradeoff curves provide a wider spectrum of designs and placement guidelines, improving the sustainability of urban watersheds.

Independent modal control technique allows to change the eigenvalues of a system, without changing its eigenvectors. From a mechanical point of view, it means it is possible to modify the natural frequencies and the damping of a n-DoF system, letting modal shapes unchanged. Independent modal control can be profitably used in active vibration control increasing the damping of the system without changing its natural frequencies and vibration modes. A control of this type can improve the dynamic performance, reduce the vibratory phenomenon (and the resulting acoustic noise) and increase the fatigue strength of the system. This work demonstrates how the performance of the control depends on the number and position of sensors and actuators used besides, obviously, on the reduced model used to synthesize the control itself. The position of both sensors and actuators is optimized through genetic algorithm to reduce spillover effects due to unmodeled modes. Theoretical aspects are supported by numerical simulations.
