Lab-on-a-Chip (LoC) devices are described as versatile, fast, accurate, and low-cost platforms for the handling, detection, characterization, and analysis of a wide range of suspended particles in water-based environments. However, for gas-based applications, particularly in atmospheric aerosols science, LoC platforms are rarely developed. This review summarizes emerging LoC devices for the classification, measurement, and identification of airborne particles, especially those known as Particulate Matter (PM), which are linked to increased morbidity and mortality levels from cardiovascular and respiratory diseases. For these devices, their operating principles and performance parameters are introduced and compared while highlighting their advantages and disadvantages. Discussing the current applications will allow us to identify challenges and determine future directions for developing more robust LoC devices to monitor and analyze airborne PM.
据介绍，片上实验室（LoC）设备是一种多功能、快速、准确、低成本的平台，可用于处理、检测、表征和分析水基环境中的各种悬浮颗粒。然而，对于气基应用，尤其是大气气溶胶科学，LoC 平台却鲜有开发。本综述总结了新出现的 LoC 设备，用于分类、测量和识别空气中的颗粒物，特别是与心血管和呼吸系统疾病发病率和死亡率增加有关的颗粒物（PM）。对于这些设备，我们将介绍其工作原理和性能参数，并对其进行比较，同时强调其优缺点。通过对当前应用的讨论，我们可以发现挑战并确定未来的发展方向，从而开发出更强大的 LoC 设备来监测和分析空气中的可吸入颗粒物。

The precision and accuracy of a Leica MultiStation 60-based QDaedalus astrogeodetic measurement system are determined through observations at two locations in Switzerland. The precision of the QDaedalus was determined as 0.1″ for the N-S and E-W deflections of the verticals (DoVs) through 118 series of observations collected over 13 nights (in a 44-day observation period) at the HEIG-VD test station. The accuracy of the QDaedalus system was established by simultaneous parallel observations over two nights using the CODIAC system at the Zimmerwald Observatory. The differences between them were found to be 0.09″ and 0.02″ for the N-S and E-W DoV components, respectively. From these results, the accuracies of both DoV components can be interpreted as 0.1″. We also found a large systematic trend in the observed N-S DoV data at the HEIG-VD test station (0.008″/day). This study is the most extensive thus far for determining the precision and accuracy of the QDaedalus system for astrogeodetic measurements; it is also the first time that QDaedalus system’s accuracy has been established using parallel observations.

The acquisition section has some serious problems to increase the speed of acquiring the Global Positioning System (GPS) signals. In this study, we propose three new methods to optimise the Doppler search space and improve the acquisition speed of the GPS signals. The experimental results represent that our proposed methods have a superior performance compared to the conventional bin-fixed method so that the first (sub-frequency band), second (multi-frequency bins), and third (integration of the first and second methods) suggested methods outperform the bin-fixed method in terms of the execution time and computational complexity by approximately 26–19%, 33–19%, and 36–20%, respectively.

Numerous temporal GIS models for cadastral data management have been proposed, and to understand the state of their art, a study that critically assesses their designs is needed. This study reviewed 11 models and noted that except with earlier designs; most of the reviewed models could store temporal land parcels with their tracks of changes. However, they lack to maintain the semantics of their data, valid times and potential records of changes, and the alternative techniques to accelerate queries. Thus, a semantical and bi-temporal modelling framework is proposed. Future studies could use the framework and focus on implementation designs to obtain more robust models.

The fit-for-purpose rural cadastre has been implemented for several years in the Amhara region of Ethiopia. There are no internationally accepted methodologies to evaluate the efficacy of rural cadastral systems in developing countries. In this study, an evaluation framework was designed from the literature review and used to assess the quality of the rural cadastral system. A mixed research method was applied. Data were secured from the pertinent participants, and descriptive statistics was used to analyze the data. The findings indicated that the framework developed for the quality assessment was found to be an essential tool to evaluate the efficacy of rural cadastral systems. The study identified the strengths, weaknesses, opportunities, and threats of the cadastral systems of the Amhara region, which underpinned the understanding of the spatial, legal, and institutional arrangements and statuses. Further, this study identified sets of indicators and good practices of the system.

For research involving customary land rights, ‘context is key’ because every context brings specific nuances for consideration. Failure to account for context runs the risk of irrelevance, unintended consequences and/or failure. We present a research method that allows context to speak: the progressive case study. The approach combines deductive case study with inductive grounded theory approaches. The results are used to propose a framework for guiding cadastral systems development in customary land rights contexts. This paper presents the methodology, which should be useful for researchers, NGOs and multinational organisations doing development programming in developing contexts.

This paper considers the regulation of three aspects of surveying profession namely, agency surveying, cadastral surveying, and valuation surveying in Kenya. The regulation boards are examined in the context of their enabling legislations. All the professions belong to one professional organisation, the Institution of Surveyors of Kenya (ISK), modelled in the like of self-regulation objectives of the Royal Institute of Chartered Surveyors (RICS). A review of the practice of professional regulations attempts to assess the level of state control in the regulation of these professions. Paper recommends injection of more self-regulatory culture in future.

Small Island Developing States (SIDS) are highly exposed to disaster risk events that frequently overwhelm their capacity to generate and share spatial information to reduce human–economic losses. The Spatial Data Infrastructure (SDI) has been widely implemented to support information sharing and management in different domains. In this paper, we aim to identify critical factors to enhance SDI performance to facilitate Disaster Risk Management (DRM) in SIDS. We make use of a three-round Delphi survey and Kendall W coefficient to assess consensus among 28 key international experts in SDI, surveying and DRM. Our results illustrate strong experts’ consensus on identifying a list of 23 most critical factors. We found that people and policy factors matter the most. The insights reported here would assist decision-makers to design roadmaps to enhance sharing of spatial knowledge to build more resilient SIDS and to support their achievement of the Sustainable Development Goals.

The nonlinear and nonstationary characteristics of satellite clock bias (SCB) have a harmful effect on the accuracy and stability of SCB forecast. To eliminate the influence of nonlinearity and non-stationarity, a hybrid forecast model was constructed that combines complementary ensemble empirical mode decomposition (CEEMD) and quadratic polynomial (QP), called CEEMD-QP. First, the SCB sequence is decomposed into several intrinsic mode function (IMF) components and one residual term by CEEMD. Second, permutation entropy (PE) and the correlation coefficient are used to quantitatively determine the IMF component with more noise and weak correlation with the original SCB signal. Finally, the SCB is reconstructed with the IMFs and residual components, and QP model is used to fit and forecast the clock bias. We adapt the observation part of ultra-rapid precise SCB data of GPS provided by IGS to forecast experiments. The results show that the CEEMD-QP method has obvious advantages of forecast accuracy and stability in short-term forecast.

The importance of evaluating cities with historical, environmental and liveability parameters have become critical for effective urban management. Modern cadastre and land administration need to register Public-Law Restrictions (PLRs) to ensure the completeness of various transactions. To develop a comprehensive PLR data model for real estate management integrated with National GDI models, this study investigates the urban-related PLRs. An interoperable data model was designed within the Management-Restriction-Regulation Zones data model as an extension with relation to the Cadastre data model. In future cadastral applications, all property-related restrictions can be accessible as in case of the designed data model.
