Saat ini terjadi penurunan yang signifikan baik secara kuantitas dan kualitas dari Ruang Terbuka Hijau (RTH), mana hal tersebut berdampak pada lingkungan hidup perkotaan. Rusaknya kawasan penyangga berupa ruang terbuka hijau menyebabkan berkurangnya penyerapan air masuk kedalam tanah sehingga memberikan dampak terjadinya bencana banjir. penelitian bertujuan untuk mengidentifikasi kemampu...

Keberadaan Ruang Terbuka Hijau (RTH) merupakan salah satu unsur penting dalam membentuk lingkungan kota yang nyaman dan sehat. Ketersediaan vegetasi taman sebagai sangat diperlukan untuk memenuhi klaim zona fasilitas serta pemeliharaannya. RTH berfungsi antara lain paru-paru kota, keindahan pusat kesehatan jasmani rekreasi alam . Penelitian ini bertujuan mengetahui keanekaragaman jenis Taman Ko...

For a graph G, its rth power G is defined as the graph with the same vertex set as G, and an edge between any two vertices whenever they are within distance r of each other in G. Motivated by a result from additive number theory, Hegarty raised the question of how many new edges G has when G is a regular, connected graph with diameter at least r. We address this question for r = 3, 6. We give a...

We design alternative dual frames for linearly reconstructing signals from Sigma-Delta (Σ∆) quantized finite frame coefficients. In the setting of sampling expansions for bandlimited functions, it is known that a stable rth order Sigma-Delta quantizer produces approximations where the approximation error is at most of order 1/λ , and λ > 1 is the oversampling ratio. We show that the counterpart...

There are several distinct two-dimensional zeolite building layers that can condense through different stacking arrangements of the layers to form various three-dimensional framework materials. All known building layers are dense layers in that they do not contain 8-membered ring (MR) or larger pores perpendicular to the two-dimensional layers. Herein, we report a new material (CIT-10) that con...
