By Shahabuddin Amerudin Abstract Mineral exploration, a complex and high-stakes endeavor rife with uncertainties, is experiencing a paradigm shift through the integration of cutting-edge geospatial analysis and the revolutionary 4D-Geographic Information System (GIS). In this review, we unravel the profound impact of these technologies on mineral exploration, shedding light on their indispensable role in mitigating risks and significantly increasing the likelihood of discovering concealed mineral deposits. Our exploration traverses a spectrum of input datasets, encompassing remote sensing, exploration geochemistry, exploration geophysics, and geological indicators. Furthermore, we delve into the pivotal stages of user-guided interpretation and predictive modeling, which play a […]

Jarak sosial dalam kelas era Covid-19 Pautan: https://malaysiagazette.com/2021/09/15/jarak-sosial-dalam-kelas-era-covid-19/ Jarak sosial dalam kelas era Covid-19 COVID-19 merupakan satu isu pendemik yang amat serius di Malaysia dan di seluruh dunia bermula pada Disember 2019. Pada 26 Ogos 2021, Malaysia telah mencatatkan satu rekod baru untuk kes harian positif Covid-19 yang tertinggi iaitu 24,599 kes. Situasi ini mencetuskan kebimbangan kepada ibu bapa untuk membenarkan anak-anak pergi kesekolah secara umumnya. Peningkatan kes ini menunjukkan terdapat sebahagianmasyarakat yang masih tidak mengikuti prosedur pengendalian standard yang telahditetapkan oleh kerajaan. Secara umumnya, virus Covid-19 disebarkan ketika individu saling berhubung rapat diantara satu dengan yang lain. Dalam usaha

  Sejauh mana jarak sosial boleh mengelakkan risiko jangkitan Covid-19? Berikut hasil kajian penuntut UTM Pautan: https://m.sinarharian.com.my/mobile-article?articleid=200755 KITA sedia maklum, penjarakan sosial pada had jarak yang ditetapkan menjadi salah satu prosedur operasi standard (SOP) yang wajib dipatuhi. Bukan sahaja di tempat awam, malah di sekolah dan institusi pengajian tinggi juga menekankan SOP sama. Sama ada dengan pendekatan penyusunan meja pada jarak yang ditetapkan atau mengehadkan jumlah pelajar dalam satu-satu kelas. Pun begitu, sejauh mana jarak sosial tersebut boleh mengelakkan risiko jangkitan Covid-19 lebih-lebih lagi pada ruang bilik kelas atau kuliah bersaiz kecil? Persoalan tersebut dibangkitkan dalam kajian yang dijalankan Gan Wei

Types of Flood Models

By • • Knowledge, Project, Public, Research, Teaching • , • 3 minutes of reading

There are several types of flood models that can be used to simulate and predict the behavior of floods. These include: Hydrological models: These models simulate the movement of water through the hydrological cycle, including precipitation, evaporation, infiltration, and runoff. Hydrological models can be used to predict the amount of water that will flow into a river or stream, and to estimate the likelihood of flooding. They typically use mathematical equations to simulate the processes involved in the hydrological cycle, such as the movement of water through the soil, the discharge of water into rivers and streams, and the movement

Database Modeling

By • • Public, Research, Teaching • , , , , , • 1 minute of reading

Using abstraction from concepts by humans to their implementation in the machine, database modeling relies generally on a three-tier model: A conceptual model involving the identification of the geographic features to be included in the database as entities/objects, the definition of their attributes, and how they relate to one another. An abstraction and objective representation of the real world independent from the DBMS software to be used. A logical model, a resulting outcome from the transformation of the conceptual model using the DBMS data model techniques (e.g., relational, object, or object-relational). A physical model, a resulting outcome from the transformation of
